Just file storage, Plex server and maybe RDP/Teamviewer to it for docs and stuff. I'd like to be able to push stuff to a tablet too.
I use 8GB RAM for the following in an ESX:
1 x Windows 2003 (Domain Controller) - 512MB RAM
1 x Windows 2008 R2 (RD Gateway) - 1GB RAM
1 x Windows 7 (Use this as a remote desktop / VDI) - 2GB RAM
1 x Arch Linux (Plex Media Server / Mumble server aka Murmur / Apache) -1GB RAM
I have other VM's but they are turned off and then on when needed.
Just need to wait for my graphics card, extra RAM and memory stick to arrive and to decide if I want to ESXi or not.
