Good mini itx cases other than the bitfenix prodigy, and the corsair 250d. It has to support an h100i, and an atx psu, along with a Asus 770. Any suggestion is a good one. Thx
The Corsair Obsidian 250D is a spectacular case for your needs, especially if you want to use a long video card, modular PSU, and the H100i (or any other large water cooler).
The only other case you may want to consider is the Node 304 by Fractal Design.
It's 2.5" smaller than the 250D in height and width, has no optical drive bay, and it will fit everything you mentioned...
BUT... (and this is very important)
in the Node 304 you cannot use a full-length GPU with a modular PSU. The reason is that GPUs longer than 9" will run flush with most...
