so i am in the market for a new computer, but my budget is laughable. so i figure i will just build one. so i go to my usual shopping spot for computer supplies... Pricewatch.com and begin looking around. I found what they call a pc with no os. so the computer comes with no windows... no big whoop. an athlon 2200 with 128 of ram and a 20 gig hard drive... for 125 dollars! there has to be a catch.
