I would have to look at how much power it 7xxx series consumes to make a judgement on that
For RAM go with G.Skill or Corsair Vengence make sure its low profile (meaning no toothy heatsink thingies)
Get a CPU cooler (Hyper 212+, Hyper 212 EVO, CM 612 are good options depending on how much OCing your going to be doing and also if you dont want to WC). I've never done WC'ing so I wouldnt be able to tell you wether it will fit or not.
Do you have an HDD picked out already? If not got with the Seagate Barracuda 1TB w/7200 RPM
For SSD go with the Crucial M4 if you plan to get one
