I present to you three bargain-basement quad-core *starter* systems. While none would win any speed or gaming prizes as-is, any would be the starting point for a decent system, using a mere two upgrades (PSU and graphics).
Acer Aspire M5630: http://www.bestbuy.com/site/olspage.jsp?skuId=8602407&type=product&id=1192232280889 (I chose the BB link because the link on Acer's own site was not cooperating)
Gateway GT5628: http://www.gateway.com/retail/gt5628.php
HP Elite m9040t: http://www.shopping.hp.com/webapp/shopping/cto.do
None include integrated graphics, and all three have *natural* GPU upgrade paths (Gateway and HP to the 8800GT, and Acer to the HD 3870) that won't force you to go through driver histrionics. All three include DL DVD burners (HP's system, naturally, throws in LightScribe support), and all three can take *standard* replacement PSUs (such as PCP&C's Silencer 750Quad: http://www.pcpower.com/power-supply/silencer-750-quad-black.html).
Acer and Gateway have the largest single hard drives (500 GB); the Gateway also has the largest amount of RAM (3 GB).
Just goes to show what can be done, even with a starter system, with judicious upgrading.
