Opinions please. I have the chance to purchase a refurbished Dell OptiPlex computer. It has: Intel P4, 2.4 GHz, 2 GB DDR RAM, 160HD 7200 RPM, Pioneer 18xDVD +R DVD RW dual layer, ATi Radeon 9550 AGP 256 MB DDR w/VGA, DVI, TV out. It comes with an 18" Dell Ultra Sharp flat panel LCD monitor, Harmon Kardon speakers, Windows XP PRO w/SP2, Windows Office XP PRO. 5 PCI slots, 8USB ports (2 frt and 4 rear), 2 serial ports, 1 parallel printer port, key board and mouse. Seller claims it is upgradeable to Windows Vista. All for $720.00. Question, I am an average user not into business computing just small time gaming and home style browsing. Is this a buy or is it a better choice to purchase a new Dell home PC and probably pay more. Thanks in advance.
