bringing this thread back from the semi-dead!!! I finally got some free time to work with this guy, I'm using Archlinux on mine good ol' command line only! So far I've got these services configured and running, Mumble (voice server like TS / Vent), unrealircd, LAMP services, ssh, ssl, and I'm working on samba now! What have you guys used yours for!?
I've got mine running on an 8gb sd card and it'll be a bit overkill, but should be good when I start to host sites and such.
