Animal hit it right on the money..
Ya go with the i5 a solid chip... Definitely a solid investment I have built 3 of them recently and all my customers have been very satisfied from their performance in anything.
I always build my systems with Liquid cooling but you might be better off.
If you are going discount than go with AMD for video.
If you want a good card than go with NVIDIA.
If you ever plan on doing a dual monitor setup make sure that you love the first monitor you get..
nill on that Power supply I suggest you get a corsair or even better antec spending money on this now will save you money in the future.. Honestly my antec has been solid for about 4 years now and I havn't had a problem with it(oh it cost me about 159 cause i got the modular one).
Was running a i7 930 before my 3770k with 3 hard drives and dual CD roms.

NZXT has some nice cases but dont buy liquid cooling from them no no. the pumping system was just uuuuugh. I RMA'ed with them for the exact same problem the pump was clicking when the cpu was getting hot. I threw it away for the fact that the RMA had the exact same problem.
All the rest is great.
