If they all "post" (meaning they will boot up to bios with no problems) you can probably resell them to someone. You can also look into a bios check program, which you can find for free if you do some research, and verify that everything is up to par. However, there are some factors to consider . How old are the machines? Do they have COA stickers? What version of windows is on the COA? Win XP machines are going to be much harder to sell in bulk since it's no longer supported by microsoft. You can also look into purchasing some hard drives (80GB is the minimum I would even consider) which might help you sell them a little faster. Depending on what you can purchase them for, the questions I posed, and the time you have, will help you figure out what to do with them....
