I know, but the reduced power goal for NB is my top priority. Every 100W
of continuous use is about 875kwh/year (73/month) @ $0.18 ~=
Getting rid of the 300W that stallion was using will help a ton, and I'd
rather get VMs or colo'd machines outside of NB. It's just not a good
space for doing servers.

Yes, I'll be making sure that performance doesn't suck.
