You don't need the i5-3570K and H100 if not overclocking. I'd save like $120 and get a i5-3470 and have basically exactly the same performance. Maybe throw a quiet $20-30 heatsink on it.
650W is also waaaaay more power than you need. You could save cash there too.
EDIT: If you want something truly quiet, i'd maybe replace the stock case fans as well.
Also, the majority of RAM brands are fine. Most are made by only a few different companies and rebranded anyway. Most brands offer a lifetime warranty as well. The ones with the best reputation in my experience though, are Corsair, Crucial, Kingston and G.Skill. Plenty of others like Geil and Mushkin are fine though.
