I agree mines being used as a wireless bridge its always on too i had 5 other running but didn't see a point in tying up all that ram and hard drives. I've already got 16 computers to maintain it wasn't a power cost issue more of a time issue it wasn't worth the few hrs a week to check up on them for there credits.
If i can figure out how to get windows or anything else if anyone has a suggestion to install on a sd card i might fire them up for the prime animal challenge
