Define 7 mid-tower case

The Define 7 is an ATX mid-tower chassis built from steel with a dark tinted tempered glass side panel. It accepts motherboards up to 285 mm E-ATX as well as standard ATX, Micro-ATX and Mini-ITX boards. The interior uses a dual-layout design that can be configured for either open water-cooling space or maximum drive density. Three Dynamic X2 GP-14 fans are included at the front and rear.

Radiator and fan limits

The default open layout supports radiators up to 420 mm for custom water-cooling loops. Nine fan positions are available across the front, top, rear and bottom, each accepting 120 mm or 140 mm fans. The top panel swaps between a sound-dampened solid steel cover and a filtered ventilation panel that adds three more fan positions. Front I/O provides one USB 3.2 Gen 2x2 Type-C, two USB 3.0, two USB 2.0 and two audio ports.

Storage capacity and headroom

In the storage layout the case holds up to 14 x 3.5" drives and 4 x 2.5" drives using the included trays and brackets. Six 3.5" trays, two 2.5" brackets and one multi-bracket come pre-installed. A single external 5.25" bay remains available for optical drives or accessories. Seven standard expansion slots plus two vertical slots give room for long graphics cards and additional add-in cards.
