Corsair CC-9011291-WW FRAME 4000D Tempered Glass White Steel Modular ATX Mid-Tower Desktop Chassis

Great case, modular to all your needs and the rail system for the fans is amazing, no blocking any airflow like others do to support 120mm and 140mm.

The only critical point is for those that still have/use HDD (you only get one sensical mount point for em, but non issue if you use SSD, you have 4x mount points for them)

At this price point you will be hard pressed to find any other solution with as much flexibility. Parts are sturdy and well designed, sheet metal bends keep them from being wobbly and a little bit thicker than some other brands. If you want the customizability of larger cases but still require a small footprint, get a frame 4000D/
