White mid-tower server chassis fits ATX, Micro-ATX and ITX boards with room for a 305 mm GPU, 170 mm cooler, two 3.5″ drives and three 2.5″ SSDs
This mid-tower server chassis accommodates ITX, M-ATX and ATX motherboards within a 205 x 340 x 428 mm aluminium-magnesium frame. A 5 mm tempered-glass left panel and 1.0 mm steel internal plates provide structural rigidity. Front-panel USB 3.0 enables fast data transfers for external storage.
Builders moving from ITX-only enclosures gain support for full-size ATX boards, CPU coolers up to 170 mm and graphics cards up to 305 mm. The jump is worthwhile when additional PCIe slots or larger coolers are required. Front mounts accept 120 mm or 240 mm liquid-cooling radiators, though a 240 mm unit reduces maximum GPU length to 255 mm.
The layout suits users assembling a first desktop, theatre PC or gaming system who need flexible drive configurations — two 3.5-inch or three 2.5-inch bays, swappable to two of each. Optional 120 mm fan positions at front, rear and bottom allow custom airflow. Buyers requiring more than three SSD bays or dual-radiator support should consider larger enclosures.

The CPU heat sink height limit is 170 mm, so any cooler up to that height will fit inside the 205 mm wide case.
Align the board to the ATX standoffs within the 305 x 245 mm tray area; using the wrong pattern leaves mounting holes unsupported.
Dust the front, rear and bottom fan mounts every few months to keep airflow through the independent heat dissipation area unobstructed.
