A lot of those items are a lot cheaper on newegg. Here's what I would go with...

Tigerdirect seemed to overprice a lot of their items. I tried to keep some of the same components, like the mobo and cpu, and as you can see, they're a lot cheaper on newegg. Also, that psu, dvd drive, and hdd you had were waay overpriced.

Budget rige, lol it out classes my expensive rig.

Anyway the original is good though you could save on special deals else where.

Try going for some DDR2 1066 to make the Quad more efficient.
