I posted that build before it was cool. Good God, I'm a hipstur.
For $550 i'd expect something similar to mine considering it's the best you can do for $550, stole the case from you though ;D
Also one more note. OP if you have the money buy two 500gb drives, instead of one 1tb drive. One for writes/renders, one for reads/storage.
I had that build saved since yesterday and the price jumped around 60 bucks :O I'm actually gonna build something similar to this, tomorrow's (March 22nd) my birthday so I might get a little cash allocated to me.
