Well if all your trying to do is get regular stuff done then go to tigerdirect.com and look at their barebone kits ....
Something along these lines http://www.tigerdirect.com/applicati...94770&CatId=31 ...
Another good thing is possibly pcpartpicker.com I know Blame had a 400+ Build but it's gear towards gaming.
My i5 was around 240, motherboard 130, ram was around 80ish that's 450 but you can find something I'm almost positive.
