I'm not sure what the difference is or which one I should download. I have a server rack I'm putting together and I don't know much about servers. I love ubuntu though. If I want to use this a work server to host things and a personal server for experimenting, which should I use?
I also might dual boot this with windows server 2008 eventually. I'm using a dell power edge 2500 with 5 scuzzy drive totaling 100gbs and maybe 2gbs of ram.
