Open-frame steel chassis fits ATX, mATX or ITX boards, two drives, 256 mm graphics cards and 360 mm water cooling with a built-in carry handle
This open-frame steel chassis supports ATX, mATX and ITX motherboards, an ATX power supply, two drive bays and graphics cards up to 256mm long. It is aimed at DIY builders who want a compact test bench or a permanent open-air server with easy component access.
The kit includes a base plate, fan stand, drive shelf, handle, screws, a hex screwdriver and a power-on cable. A press-to-start button turns the system on and a long press shuts it down, so no separate case switch wiring is required. The open layout removes cable-routing channels, so builders must plan power and data cables carefully to avoid airflow blockage.
The frame mounts either three 12cm fans or a 360mm water-cooling radiator directly in the airflow path. With no side panels to trap heat, exhaust leaves immediately, keeping temperatures stable during long rendering or compute sessions. Dust accumulates faster than in closed cases, so regular cleaning is necessary for consistent thermal performance.

Press the bounce button to power on the system and long-press it to power off; successful boot and shutdown confirm the power cable and switch are working.
The box includes a base plate, fan stand, hard-disk shelf, handle, two screws, a hex screwdriver, a power-on cable and an instruction manual; you must provide an ATX power supply, motherboard, CPU, memory, storage drives and graphics card.
It accommodates ATX, micro-ATX and ITX motherboards and accepts full-height graphics cards up to 256 mm in length.
