DELL OptiPlex 755 SFF Desktop PC, B Grade, Scratch & Dent Core 2 Duo 2.3GHz 2GB 80GB HDD Capacity Windows 7 Professional

Pros: Clean case and components, worked on arrival, comes with Windows 7 Pro CDs and installed (32 bit... I'll fix that later after adding RAM). Makes a perfect media center PC to replace my old full-size tower.

Cons: I had an issue installing a video card (HD 7750 1GB): during installation I kept getting a BSOD - something about plug and play issues... I suspected it might have something to do with power consumption, so after failing to install it four times, I disconnected the optical drive. The installation then went fine. It might have been magic... because I can't really explain why a video card that only draws about 40W would overtax a system/power source (275W) like this.

Other Thoughts: I purchased this to replace a circa 2003 Dell Optiplex GX270 that has been faithful as a "media center PC" for about six years. Like another reviewer, I added an HD 7750 1GB (about $100) low profile video card. I am also thinking about buying 2GB of RAM (DDR2 PC2 8500, about $45) and installing Windows 7 64 bit to take advantage of all 4GB. A very nice computer for about $300 after adding an over-powered video card (for the PC) and RAM.

Pros: makes a great computer for anything! I use it at LAN party's ;) with some upgrades. ram,hdd,video card. PUT A LOW PROFILE HD7750 in it! bottleneck? who cares lol

Cons: lowwww psu.

Other Thoughts: buy it!:)
