So I have my heart set on this case but I'm struggling with the PSU. 500-650W should be adequate, I've got an i5-4460 and an R9 285 2Gb. I initially just picked a Corsair but I've been warned against it being a lottery on qualty. XFX was suggested and looked good but I'm having trouble nailing down the dimensions on some, even 163mm simply won't fit in the case without DIY that I want to avoid. Modular (Semi or Full) would be nice but not crucial, budget bothers me more to be honest. Any suggestions?
