The Vector V100 comes with 4 pre-installed 120mm ARGB PWM fans using hydraulic bearings, each capable of up to 1800 RPM, 61.47-60.4 CFM airflow, and 2.54-2.17 mm-H2O air pressure, with noise ranging 26.5-30.8 dBA depending on speed. A 26-LED ARGB strip adds further lighting, and both fans and strip daisy-chain together for a simpler cable run than wiring each component separately.

• 4x 120mm ARGB PWM fans included, hydraulic bearing design
• 26-LED ARGB strip with full spectrum color control
• Daisy-chain connectivity reduces individual cable runs

Fan and strip lighting sync with motherboard ARGB software, so color and effects can match other components already running compatible lighting ecosystems.

The case supports ATX, Micro-ATX, Mini-ITX, and back-connect ATX or Micro-ATX motherboards, giving builders the option of a standard layout or a back-connect board for hidden cable routing behind the tray. Tool-less mounting on each side panel speeds up the build process, since panels come off without reaching for a screwdriver for routine access.

• Back-connect motherboard support for cleaner cable management
• Tool-less side panel mounting mechanism
• Included GPU support bracket for heavier graphics cards

E-ATX and other oversized motherboard formats are not on the supported list, so builders working with larger boards will need to confirm fit before assembling the rest of the build.

Internal clearance is built for high-end hardware: graphics cards up to 420mm, CPU air coolers up to 178mm tall, and a top-mounted radiator up to 360mm. That headroom leaves room to move from air cooling to a 360mm liquid loop, or to swap in a longer flagship GPU later, without the case itself becoming the limiting factor.

• 420mm max GPU length clearance
• 178mm max CPU cooler height
• 360mm top radiator support

A GPU support bracket is included to help offset the weight of longer graphics cards over time, reducing sag as heavier cards are installed.

This ATX mid tower measures roughly 17.6 inches deep, 8.46 inches wide and 18.46 inches tall, and combines a metal frame with a genuine walnut or oak wood front panel and a tempered glass side panel for viewing internal components. Two 140mm PWM fans come pre-installed, giving a working airflow setup before adding any aftermarket cooling.

• Metal frame paired with genuine wood front panel accents, cut from sustainably sourced walnut or oak
• Tempered glass side panel resists scratching while showing off internal components
• 2 pre-installed 140mm PWM fans provide baseline airflow without extra purchases

Front panel access uses an open-mesh design behind the wood slats for intake airflow, rather than a fully solid wood front that would restrict air movement.

The case supports ATX, mATX, and ITX motherboards in one shared layout, and GPUs up to 355mm in length fit with a standard configuration. Installing a 360mm radiator in the front reduces available GPU clearance to 300mm, so radiator size and GPU length need to be balanced against each other during planning.

• 355mm maximum GPU length in standard configuration without a front radiator
• 300mm GPU clearance remains available even with a 360mm front radiator installed
• 7 bridgeless expansion slots support multi-card or angled component layouts

Because GPU clearance changes depending on front radiator size, builders planning a large air-cooled GPU alongside front liquid cooling should measure both components against the case's clearance figures before buying.

Storage starts with 2 combined 3.5-inch/2.5-inch drive mounts plus 2 dedicated 2.5-inch mounts, covering a mix of traditional hard drives and SSDs without needing extra brackets. A front Type-C USB port supports newer peripherals and fast external transfers directly from the case front panel, and the interior layout leaves room for additional fans or radiators as a build's cooling needs grow.

• 4 total drive mounts, 2 combined plus 2 dedicated 2.5-inch, support a mixed HDD/SSD setup
• Front-panel USB Type-C port supports modern peripheral connections
• Removable side panels and a clip-off top panel simplify future internal upgrades

Because the drive mount count is fixed rather than expandable, builds needing more than 4 total drives will need external storage or a different case.

Three 120 mm addressable PWM fans ship pre-installed behind a perforated steel front panel. The perforation uses a three-dimensional Y pattern designed to give air a low-obstruction path rather than forcing it through a flat mesh grille.

• Front rails take fans up to 200 mm
• Roof rails take fans up to 140 mm
• Side mounting available once the inner panel is removed
• Fans support a Zero RPM mode for near-silent behaviour at low load

The rail system is the useful part. Rather than fixed screw holes, the rails let you slide a fan to sit exactly over a graphics card or a radiator inlet. If you are running a high-power card, adding a rear exhaust fan is the first upgrade worth making, since all three included fans are intake.

This is a mid-tower ATX chassis built from alloy steel with aluminium elements, sized for a mainstream tower build rather than an extended workstation board.

• Supports ATX, micro ATX and mini ITX boards
• Supports rear-connector boards: ASUS BTF, MSI Project Zero, Gigabyte Stealth
• Roof radiator mounting up to 140 mm fan sizes
• The internal side panel doubles as a cable cover or a fan mount

Back-connect board support is the detail worth flagging. Those boards move every connector to the rear of the tray, which needs matching pass-through cut-outs in the case to work at all. If you are planning that style of build, this chassis is already prepared for it. For a conventional board, the same cut-outs simply serve as generous cable routing.

The distinguishing idea here is a chassis assembled from replaceable sections rather than a single riveted shell. Panels, the board tray and the front input panel are designed to come off and be swapped for alternatives.

• The motherboard tray can be exchanged for a billet aluminium version
• The front input panel can be swapped for one with a different port arrangement
• Side panels and rails come apart for access during a build

Two things follow from that. Building is easier, because you can strip the case back to a skeleton and reassemble around the components. And the case can change later without being replaced. The trade is that every alternative module is bought separately, so the version in the box is what you get until you choose to add to it.

The NZXT H5 Flow - Compact ATX Mid-Tower PC Case - Black provides essential hardware performance for custom PC builds and workstation upgrades. Engineered to manage demanding electrical or thermal workloads, this model incorporates EXCEPTIONAL GPU COOLING-The PSU shroud is perforated on the side and together with LARGE RADIATOR SUPPORT-Supports up to a 360mm radiator in front and a.

The iconic angular mesh design prioritizes filtered airflow over traditional enclosure aesthetics. The front mesh panel is hinged with removable nylon filter enabling easy maintenance while providing optimal cooling performance. Bold stealth-inspired aesthetic appeals to gaming and high-performance PC builders.

• Iconic angular mesh filters airflow while providing distinctive visual appearance
• Hinged mesh front with removable nylon filter simplifies dust maintenance significantly
• Radiator support: 360 mm front, 420 mm top, 280 mm base enables multi-radiator configurations
• Flexible cooling layout accommodates air and liquid cooling simultaneously
• Optimized internal airflow paths maximize heat dissipation efficiency

The radiator support flexibility enables custom water cooling configurations with multiple radiators for extreme cooling performance. Air cooling users benefit from large mesh intake area and multiple fan options.

The adaptable dual-layout interior supports both small storage arrays and massive drive configurations simultaneously. Support for 11 hard drives plus 4 SSDs with 9 included brackets accommodates everything from minimal configurations to extreme NAS-style storage arrays.

• 11 hard drive mounts enable large storage capacity in single case
• 4 SSD mounts plus 9 included brackets provide flexible SSD placement options
• Adaptable dual-layout supports E-ATX boards up to 285 mm width

Bolt-free flush tempered glass design provides stunning visual presentation while requiring careful handling. Tool-free bezel and fully removable top panel grant excellent interior access for component installation and cooling system maintenance.

• Bolt-free tempered glass window provides seamless aesthetic appearance
• Tool-free front bezel enables quick access without screwdriver requirement
• Fully removable top panel grants complete interior access for installation and maintenance
• Tether-free bezel design eliminates cable management attachment points
• Professional appearance suitable for custom builds and demonstration showcases

The tempered glass construction prioritizes aesthetics over durability. Accidental breakage requires complete replacement without repair options. Installation must be done carefully to avoid stress cracks. This comprehensive approach ensures consistent performance throughout extended operational scenarios.

The PA602 pairs a 15.5mm open front grill at 45% porosity with dual 200 x 38mm front fans and a 140mm rear exhaust fan for a low-resistance intake path. Two internal air deflectors redirect incoming air toward the motherboard and other heat-generating components rather than letting it escape unused.

• Front fans: two 200 x 38mm, extra-thick for maximum intake
• Rear fan: 140 x 28mm exhaust
• Radiator support: up to 420mm for AIO or custom loops

A front panel IR dust indicator reminds the owner when the intake filter needs cleaning to keep airflow at its rated level.

Case dimensions run 23.35"D x 9.65"W x 22.05"H, built to fit E-ATX motherboards along with the largest current graphics cards. A dedicated GPU holder supports heavy cards either horizontally or vertically, and tool-less PCIe mounting means expansion cards click into place without a screwdriver.

• Board support: E-ATX and smaller form factors
• GPU clearance: ample room for full-length cards, horizontal or vertical
• Materials: alloy steel, plastic and tempered glass construction

A dedicated Wi-Fi antenna compartment keeps external antennas tidy without cluttering the rear I/O panel.

Front I/O includes a 20Gbps USB-C port alongside a Power Lock Latch and 2-section PWM fan control, giving builders headroom to add fans or an AIO cooler later without rewiring the whole case. The built-in fan hub centralizes PWM connections for easier expansion.

• USB-C: 20Gbps front-panel port
• Fan hub: built-in PWM management for future fan additions
• Warranty: 2 years from ASUS

Because the chassis already supports a 420mm radiator and multiple fan positions, most cooling upgrades can be added later without swapping the case itself.

The shell measures 15.35 inches deep, 8.07 inches wide and 18.98 inches tall, the standard mid-tower envelope for a full ATX motherboard. Micro-ATX and mini-ITX boards drop onto the same standoffs, leaving spare room behind the tray for cable routing. Steel forms the frame and tempered glass the left panel, so the empty chassis has real mass before any hardware goes in. Front I/O covers two USB 3.0 ports plus audio, enough for a headset and an external drive without reaching behind the desk. Three numbers are worth checking before ordering: graphics card length, CPU cooler height and radiator thickness. The polygonal mesh front means intake is not choked by a solid door, but a 360 mm radiator with thick fans still deserves measuring against your board layout.

Six PWM ARGB fans arrive already mounted, which is unusual since most mid-towers ship with one or two. Two separate things need controlling:

• PWM speed runs from motherboard fan headers, so the fans idle slowly and ramp under load instead of spinning flat out all day.
• Addressable lighting needs a 3-pin 5 V ARGB header. Each fan then addresses 16.8 million colours through your board maker software.

Boards carrying only a 4-pin 12 V RGB header cannot drive addressable fans; lighting will default to a fixed pattern or need a separate controller. Count headers first, because six fans plus a CPU cooler is more connectors than many entry boards provide, and a PWM splitter hub is the simple fix. Upgraded bearings are quoted for service life, and the frames are standard 120 mm if you swap them later.

The side glass hangs on magnets with a metal pull ring, so it swings open like a door rather than needing four thumbscrews removed and a heavy panel balanced against the desk. That changes maintenance habits: a monthly wipe of the graphics card shroud and a blast through the front mesh becomes a two-minute job instead of a weekend chore. Dust filters still need pulling and rinsing, and they must be completely dry before refitting. The open door also gives quick access for swapping a card or reseating a memory stick without dragging the tower off the desk. Owners who display figures or models inside the case get the same benefit, since the door opens without disturbing cable routing. Clean the glass with a microfibre cloth, as household sprays can haze the coating over time.

The FLP02 measures 19.5 inches deep by 9.2 inches wide by 18.6 inches high, built around a metal chassis with a retro-inspired front panel. A dedicated Turbo button on the front jumps all connected fans to full speed instantly, bypassing software fan curves when extra cooling is needed on demand.

• Metal construction with a compact 9.2-inch width footprint
• Turbo button for instant full-speed cooling override
• Three front 5.25-inch expansion bays

The narrow width paired with a deeper chassis favors builds that prioritize airflow and radiator space over a wide, panoramic side-panel display.

Cooling support centers on 360mm liquid cooling radiator compatibility, giving room for a large all-in-one cooler or custom loop radiator without cramming components. Graphics card clearance extends to 386mm in length, enough for most current flagship GPUs, including longer triple-fan cards.

• Supports up to 360mm liquid cooling radiators
• Graphics card clearance up to 386mm in length
• Metal frame supports demanding, high-heat multi-core builds

Buyers running the largest current flagship cards should double check exact card length against the 386mm limit before ordering, since a handful of oversized triple-slot cards exceed that figure.

Three front 5.25-inch expansion bays are compatible with a hot-swap drive adapter cage, useful for content creators or archivists who need to swap drives frequently without opening the case. Top-mounted I/O keeps everyday connections within reach rather than routing them to the rear.

• Three 5.25-inch front bays, hot-swap cage compatible
• Top I/O: 1 USB Type-C port, 2 USB 3.0 ports
• 1 combo audio jack on the top panel

The 5.25-inch bay format is less common on modern cases, so this layout suits builders who specifically want optical or hot-swap bay support rather than a minimalist bay-free design.

The three numbers that decide whether your parts fit are stated plainly, and they are generous for a Micro-ATX chassis.

• GPU length: 360 mm. That covers almost every triple-fan card on the market, including large models.
• CPU cooler height: 159 mm. Enough for most mainstream tower coolers, though the very tallest dual-tower designs will foul the side panel.
• PSU length: 160 mm. Standard ATX units are typically 140 to 160 mm, so measure before choosing a high-wattage or fully modular supply.

Board support covers Micro-ATX and Mini-ITX. A Mini-ITX build in here leaves a lot of empty space but gains easy cable routing. Check graphics card thickness too, since a 3-slot card in a Micro-ATX layout can cover the lower expansion slots.

The design philosophy is open thermal, meaning perforation on every side rather than a sealed front panel with a narrow intake slot.

• Up to five fan positions in total across front, top and rear mounts.
• A 240 mm liquid cooler radiator is supported, which is the practical ceiling for a chassis this size.
• Magnetic dust filters cover the intakes and pull off for a rinse under a tap.

Only one fan comes fitted at the rear, so plan on adding intakes. Two 120 mm fans at the front pulling in, with the stock rear fan exhausting, gives the classic front-to-back path and slight positive pressure that keeps dust on the filters rather than on the components. Clean those filters every couple of months if the case sits on carpet.

The modular I/O panel is the unusual feature. Rather than being fixed at the top front, it can be repositioned to the front, top or bottom on either side of the chassis.

• Case on the floor to your left? Move the ports to the top-right so the leads do not stretch.
• Case on a desk? Front mounting keeps a USB stick within easy reach.

Behind the motherboard tray there is room for cable routing, though it is tighter than a full ATX tower, so a non-modular power supply leaves a bundle of unused leads to hide. The transparent side panel means that mess is visible, so it is worth taking the extra fifteen minutes with cable ties. Standoffs are pre-fitted for the Micro-ATX pattern, which saves a step at the start of the build.
