Build Platform

The Corn Electronics MOD3 is an ATX full-tower chassis built for custom water-cooling enthusiasts and internet-cafe operators who want an open aluminium-and-glass showcase. It accepts EATX, ATX, micro-ATX and mini-ITX motherboards while keeping the internal layout completely visible through 4.0 mm tempered glass.

Capacity and Headroom

Graphics cards up to 400 mm long and CPU coolers up to 170 mm tall fit without interference, and the PSU bay takes standard ATX units no longer than 195 mm. Drive mounts hold either two 2.5-inch SSDs plus one 3.5-inch HDD or three 2.5-inch SSDs. Top and front positions each support three 120 mm fans or 120, 240 and 360 mm radiators for heavy liquid-cooling loads.

Build Integration

Front I/O provides two USB 3.0 ports plus separate audio and microphone jacks, and seven expansion slots give room for multi-GPU or add-in cards. The 2.5 mm and 2.0 mm aluminium structure with double-sided sand-blasted anodising adds rigidity while the open-frame design leaves cable routing unrestricted. Builders who need more than three 2.5-inch drives or a second 3.5-inch bay will need a different chassis.

Questions about this item

Will my existing EATX motherboard fit inside the MOD3 without blocking the 400 mm GPU clearance?

The case supports EATX, ATX, MATX and ITX boards while still allowing graphics cards up to 400 mm long and CPU coolers up to 170 mm tall.

How can I confirm the front-panel USB 3.0 ports are active after building in the MOD3?

Connect the internal USB 3.0 header to the motherboard, then plug a USB 3.0 device into either front port and verify it enumerates at 5 Gbps in the OS.

Which fans and radiators are included with the MOD3 and what must I purchase separately?

The case ships with no fans or radiators; it provides mounting points for three 120 mm fans at the front, three 120 mm fans at the top, and 120, 240 or 360 mm radiators in those same locations.
