I had a look around the site, its pretty impresive what they have done to get users up and running. I now have a Fedora 14 install problem to work out, it keep freezing on install. I might download the ISO again.
I think I am going to run these OS's on mine:
XP sp3
WIndows Home Server
Small Business 2003 (just for playing around with)
Fedora 14
Unbuntu 10
Probably only run max two at a time until I get more ram.
No all I need to do is get power and network in to my loft.
