Their part selection still leaves another $7.05 available, which means you could afford a drive up to $46.04. For that price, you could get a Hitachi Deskstar 500GB 7200RPM drive for $42.99 ($0.086/GB). If you don't like Hitachi, there is a Western Digital Caviar Blue 500GB for $44.95 ($0.09/GB).
During the evenings I've been working on a site that tracks hard drive prices and price/capacity ratios (http://pcpartpicker.com/partscharts/internal-hard-drive/over...). If you're willing to spend over $80, you can get drives at $0.053/GB.
Is implementing dual-core, quad-core price ratio CPU on your list of TODO, and how soon will you implement it?
For CPUs, were you looking for a price/core ratio?
And yeah - assembling PC yourself gives you opportunity to drop microsoft tax completely!
The missing peripherals will probably add at least $100 to the total.
