Dell Dimension 4550 Desktop PC Windows XP Bargain Computer ?

Fully working order, clear signs of use, front plate has been broken off but in no way effects the computers use (purely aesthetic). Will come pre-loaded with Windows XP Home Edition. Completely standard except for 512 RAM upgrade. Front USB ports are a bit questionable however there are several in the back anyway. Comes with power cable. Priced to sell, contact me for further details
