The motherboard has worked 100% percent for me; all the ports work and the UEFI bios is amazing... my only complaint is the motherboard shield for this was an utter piece of crap that I nearly snapped in half putting in.
The keyboard and mouse are amazing picked them up very cheap for boxing day; the mechanical keys on the keyboard make it awesome to use for long gaming sessions which I am happy about!
My big complaint however is the case, the case is horrible and will most likely pick up a different one, I can't mount my third spectre fan on the inside of the side of the case because the 6 pin's on the 670 prevent me from doing so "sigh", luckily I was able to mount the fan on the outside of the case but it looks ugly as hell (at-least it cools -.-)
Games so far have been AMAZING!, the two gtx670's continue to impress me everyday by their performance and its relativity low temperatures (On Farcry 3 with ultra setting's it never goes above 65 Degrees! and this is for 3-4 hour sessions!)
OH and the reason for i7 over the i5 is because there was a 20$ price range difference because of an amazing sale and I said why the hell not :D, The computer minus the monitors and A40's costed me a combined total of 1350$ I LOVE BOXING DAY!@
(850w is overkill but was cheaper because of a sale)
