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. PC builders and system integrators will benefit from the efficient internal layout, which simplifies system assembly while supporting high operational stability. The design helps maintain consistent hardware responsiveness across intensive computing tasks, gaming sessions, and daily multitasking workloads. Physical dimensions measuring 8.86"D x 16.93"W x 18.31"H allow for straightforward spatial planning prior to final placement.

Built using resilient structural components, this unit features a sturdy outer housing engineered to resist operational wear. Precision manufacturing ensures that all joints and surface connections remain firmly aligned during regular daily activity. HIGH-PERFORMANCE AIRFLOW-Ultra-fine mesh on the top, front, and side reinforces overall physical stability over extended service periods. Premium Metal construction maintains structural integrity and cosmetic appearance under routine handling. Structural integrity remains firm throughout regular usage, giving owners peace of mind. Maintaining adequate interior case airflow and clean ventilation ports preserves peak hardware efficiency during heavy processing workloads.

Three 120 mm PWM fans arrive at the front, and the sliding rail system decides where anything else goes.

• Rails slide along their length, so fans sit exactly where you want rather than on fixed holes
• Front positions take fans up to 200 mm, while the roof takes up to 140 mm
• Steel front panel is perforated in a three-dimensional Y pattern for low restriction
• The internal side panel lifts out to expose side fan mounting

The sliding rail is the genuinely useful part. On a normal case, three 120 mm fans sit in three fixed slots and the top one often blows into the roof rather than at the graphics card. Here the whole stack shifts up or down an inch to aim air where the heat actually is. Zero RPM mode stops the fans entirely at low load.

The chassis measures 19.17 in deep, 19.13 in tall and 9.41 in wide, wider and longer than the previous 4000D generation.

• Graphics cards to 430 mm with the front fans removed
• Card width to 140 mm with standard power cables, or 158 mm using a 90-degree adapter
• Dual 360 mm radiator support, front and roof
• Reverse-connector motherboards are supported for hidden cable routing

That extra width is why current flagship cards fit without pressing the power cable against the glass, which has been the failure point on older mid-towers. If your card uses a top-mounted 12V-2x6 connector, check against the 90-degree adapter figure rather than the standard one, because the cable bend is what actually decides whether the panel closes.

The modular frame system is the reason this case exists: major panels attach as replaceable modules rather than being riveted in place.

• The motherboard tray can be swapped for a different material or layout
• The front I/O panel can be changed for one with a different port mix
• Front and side panels come off as units for cleaning or replacement
• Support for reverse-connector boards means the same shell suits either wiring style

In practice this means a chassis that adapts as the build changes rather than being replaced. The trade is that the modules are specific to this family and are ordered separately, so the flexibility only pays off if you actually intend to use it. For a single build that never changes, the standard configuration is all you need.

Supports extreme cooling configurations with up to 12 fan slots total. Pre-installed fans include 3x Tranquil 140mm PWM at front, 2x P12R PWM reverse fans on power supply shroud, and 1x Tranquil 140mm in rear.

Radiator Support:

• Simultaneous 420mm front + 360mm top radiator mounting
• Independent cooling zones with removable brackets
• Front, top, and PSU shroud bracket removal for custom setups

Innovative iShift PSU mount rotates 90 degrees for optimized cable management and airflow distribution. High-efficiency multi-directional vent design reduces hot spots throughout the chassis.

Multi-material construction combines metal structural integrity with tempered glass side panels and walnut wood accents for premium aesthetics. Removable cooling brackets on top, front, and PSU shroud enable customization.

Key Features:

• Real-time CPU and GPU temperature display on chassis
• Tempered glass panels for component showcase
• iShift PSU 90-degree mount reduces cable clutter
• Walnut wood aesthetic panel adds unique styling

Supports simultaneous installation of 420mm and 360mm radiators without conflict. Premium construction supports heavy video cards and custom water-cooling loops.

Full E-ATX compatibility means this tower accommodates the largest motherboards and most powerful components. Exceptional vertical space (21.45 inches) ensures unrestricted component clearance for premium builds.

• Full E-ATX motherboard support
• Space for tall RAM modules with heatsinks
• Multiple large GPU support configurations
• Enthusiast-grade power supplies up to 1200W

Best suited for water-cooling enthusiasts, high-end gaming systems, and workstations requiring dual radiator loops. Not ideal for compact desk setups or users building minimum-footprint systems.

The H9 Flow RGB+ measures 20.08 x 19.29 x 12.6 inches and uses a dual-chamber layout built from alloy steel with wraparound tempered glass panels. It ships with 7 RGB fans pre-installed: six 140mm F420 RGB Core units and one 120mm F120 RGB Core fan in the rear, all managed through an included NZXT Control Hub.

• Total fan capacity reaches 10 fans: up to nine 140mm across the top, front-right and bottom, plus one 120mm at the rear.
• Perforated steel panels and angled front-right fans are positioned for airflow rather than pure aesthetics.
• Extra-wide cable channels and Velcro straps are built in for cable management.

The dual-chamber design keeps the PSU and drive bays visually and thermally separated from the CPU and GPU area, which most single-chamber cases don't offer.

This case fits standard ATX motherboards and supports back-connect boards like ASUS BTF and MSI Project Zero for a cable-free front panel look, in addition to conventional layouts. Graphics card clearance extends to 435mm, enough room for the largest current flagship GPUs without trimming cables or repositioning drive cages.

• Radiator support reaches 420mm on both the top and front-right panels for large liquid cooling loops.
• Standard motherboards without back-connect headers install normally, just without the cable-free routing benefit.
• The included Control Hub manages fan and RGB connections without needing a separate motherboard RGB header for each fan.

Before buying a back-connect motherboard specifically for this case, confirm the board's connector layout matches NZXT's supported back-connect standard rather than assuming universal compatibility.

With 10-fan capacity and support for up to a 420mm radiator on 2 separate panels, this case leaves significant room to add cooling hardware well beyond the 7 fans included at purchase. The dual-chamber layout also gives space to add extra drives or a bigger PSU later without redoing the whole build.

• Mesh panels are designed to maximize airflow while still filtering out dust.
• Extra-wide cable channels and tie-down points make future component swaps easier to route cleanly.
• GPU clearance of 435mm covers essentially any current graphics card upgrade.

Because the case already ships fully populated with 7 fans, later upgrades are more about swapping in a bigger radiator or additional storage than adding basic case cooling.

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.
