Airflow is the design brief here, and the fan mounting reflects it.

• Four fans included: three 140 mm units angled in the front-right chamber plus one 120 mm exhaust at the rear.
• Total capacity is nine 140 mm fans across top, front-right and bottom, plus the single 120 mm rear position.
• 420 mm radiators fit on both the top and the front-right, so a large liquid loop has two mounting choices.
• Perforated mesh panels with dust filtering feed the intakes rather than restricting them.

The angled front-right fans push air directly across the graphics card and motherboard rather than into the side of a drive cage, which is the practical benefit of moving the power supply into its own chamber.

Measure your parts against these numbers before committing.

• Graphics cards up to 435 mm long fit, which accommodates the largest current triple-fan designs.
• The case supports ATX boards and is back-connect ready, so rear-connector boards such as BTF and Project Zero designs work without visible cabling.
• External dimensions are 20.08 x 19.29 x 12.6 in, so allow desk or floor space accordingly.
• Drives and the power supply live in the second chamber, keeping the main compartment free of cages.

There is no 5.25 in bay. If you still use an optical drive, a fan controller with a front display, or a hot-swap bay, this chassis will not house them and an external USB alternative is the answer.

The dual-chamber layout exists largely to make cabling easier.

• Extra-wide routing channels run behind the motherboard tray, with Velcro straps and tie-down points already fitted.
• The power supply and drives sit in the rear chamber, so their cables never cross the visible area.
• Wraparound tempered glass on two sides puts the front corner on show, which raises the standard for tidy routing at the top of the board.
• Paired with a back-connect motherboard, the main compartment can be built with almost no visible cables at all.

One point to plan for: the four included fans are 3-pin DC types. If you want fine speed curves rather than voltage control, allow for a fan hub or PWM replacements when you specify the build.

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.

The Fractal Design Meshify 2 Black ATX Flexible Mid Tower provides essential hardware performance for custom PC builds and workstation upgrades. Engineered to manage demanding electrical or thermal workloads, this model incorporates Iconic angular mesh front provides filtered airflow with a bold, together with Room for GPUs up to 360 mm with a 240 mm radiator in the top, or up to.

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.
