The Corsair 3200D RS ARGB is the case to buy when the parts budget should go to the GPU. At $69.99 it ships with three RS120 ARGB fans, so most builds need no extra fans on day one, and it has mounts for nine 120mm fans in total, including one angled at the graphics card.
The clearances are generous for the price. Corsair lists 400mm of GPU length, or 375mm with front fans fitted, 165mm of CPU cooler height and 360mm radiators at the top or the front. It also supports reverse-connector motherboards, which hide power and fan plugs on the back of the board, and includes a GPU anti-sag arm.
The savings show in a few places. The front panel has one fast USB-C port but only a single USB 2.0 Type-A, which is thin for anyone plugging in flash drives and a headset. Cable space behind the tray is 24mm, there is no vertical GPU mount, and the warranty is 2 years. With 70 retailer reviews it has the shortest track record here. None of that outweighs the fit you get for under $70.
