I have 10 Dell Optiplex GX240 and GX260 desktops. The CPU's are as follows 1.5ghz (2), 1.6ghz (3), 1.8ghz (5) and at least 128mb of RAM (some have 256mb). They take SDRAM PC133 so those would be a super cheap upgrade. Most have a 64mb ATI video card in the AGP slot along with at least a 20 gb hard drive. The OS on them are Xubuntu which runs great on the system but if you much rather have XP then I can do that as well. If this is going to be a second PC which wont run any specific Windows only games and you plan on surfing the internet and checking emails then I would recommend keeping the Linux OS. I can easily show you the basics of running it. I am asking $75.00 per desktop. Aslo comes with a CRT monitor 15 or 17 inch.
