I have just gained posession of about 15 working PC's that have come out of an office environment as part of some work I was doing for them. I am planning on selling them on ebay. Don't spose they'll make more than 30-40 each but it's better than scrapping them. Problem is they all have WinXP on them but no licenses, disks etc. I don't want to break the law so will reformat them before sale. I was wondering about sticking Linux on there just so I can say they are up and running but know nothing about it or where to get it from. I thought it was all free but notice Red Hat are selling it! So, basically is there somewhere I can download a completely free, unlicensed version, stick it on all 15 PC's and sell them within the law? I also see some PC retailers are offering Linux free with their PC's so I guess they must be getting it somewhere. Could some kind person explain to me the ins and outs of this and maybe give me a link to a download site?
