Ok its done the problem was that the plastic washers supplied by corsair were 2 mm to short and after replacing them with 4.5mm thick, 9mm2 neoprene rubber squares with holes I can happily say that my temps are perfectly acceptable.
Cool, glad you sorted it out. If temps start getting bad when you want to overclock then a delid might be worth it down the line, but that's down to you. I'm tempted to get a 6700k next to overclock but I'm kind of waiting for a naked mount for it.
Ideally yes you would want to apply a stick on stencil/vinyl and scuff the exposed surfaces with a scotch brite pad to give it some bite and cleanoff the surface before applying spray paint over the stencil.
i've refurbed a tiny dtx formfactor case with two 5.25" bays, a 3.5" bay and a 2.5" bay in a size smaller than linus' insane compact nas. in such a tiny space having small parts is a gift of the gods.
And also a waste of money. He will not need more then the 850W version, even with two 980s both overclocked along with the CPU. Even the 750 will be enough.
This is a good modular PSU http://www.amazon.com/EVGA-SuperNOVA-1000G2-ATX12V-120-G2-1000-XR/dp/B00CGYCNG2/ref=sr_1_2?ie=UTF8&qid=1416877311&sr=8-2&keywords=supernova+1000
