First question - not sure why you are concerned about HDMI on your motherboard when you are also getting a GTX 760?
Second question - what fan on the motherboard are you asking about? I'm assuming the CPU cooler? The CPU fan connector on motherboards these days are temp controlled.
I would do Windows on an SSD, games on at least
a terabyte standard hard drive. Go bigger if you are a compulsive Steam buyer, and if you aren't sure if you are, plan to be.
RAM is cheap, might as well go for 16gigs and be done with it. Some disagree, but you don't seem like you are trying to cut corners.
Power supply - take a gander at this page
and go for a tier one if price isn't an issue. For SLI, make sure it's SLI certified - I would guess all the tier ones in the 700+ watt range are.
Lastly, 360 controller compatibility, wired or wireless, is easy. Don't worry about that at all.
That's all I got - others should have good suggestions. Good luck!
