Built a tower with a Corsair 250D mITX case. Despite being mITX, it's actually much bigger than I expected compared to my EVGA Hadron Air.
Good thing with the 250D though is that there's a lot of ventilation in the case. You can also stick a 240mm radiator in it like the Corsair H100i.
Don't buy the EVGA 750W PSU on sale though. Despite having a nice price tag and it being semi-modular, it's noisy like an airplane jet.

I got this Seasonic instead. 80+ Gold, and it's super nice and quiet since the fan only turns on during heavier loads.
