This system is a solid performer. I have used this computer for over a year without issue. The only problem I had was configuring multiple monitors. The onboard video is AGP and the video card is PCI Express. The Bios automatically disables the AGP bus when a PCI Express card is added. There is no way around this. The only way I was able to make this work was with a pci card and a universal low profile kit (because normal Low Profile cards don't fit in the case correctly).Other than that I have been quite pleased with the system. Mine is configured with a 500 gb hard drive, 512 mb ddr Ram and a 2.4 GHZ Pentium D processor running XP Professional. System performance is what would be expected with these specifications. This desktop is probably best suited for a business environment due to the case dimensions and upgrade restrictions. The system has eight usb ports (six on the back and two on the front of the case). Not a bad system for the price.
