Honestly, I've been looking at the answers for a while now and I've noticed that you don't need all that memory, as long as you are not multitasking like crazy you'll be fine, I have a 4GB RAM and I can host a MC server with no lag.
EDIT: I also have windows 7 cracked and it runs fine, find yourself a good torrent, get a registry keygen and you will have no problems!
