I bought my last rig from newegg - parts and then put it together. For my newest one, I went to Frys to buy an off-the-shelf box and was pleasantly surprised that I could get a very powerful machine for $800 or so. Frys and Microcenter offer great choices in Dallas (where I am) and I'd assume elsewhere if you have 'em.
