Okay, I'll probably leave it open or put the same blanking plate on it as
the current one.

The Travla has dual 220W PSUs but the system is a Jetway 2GHz C7 processor
and their website reckons on 20W power draw, coupled with 2x2.5" SATA
drives at 3W apiece. I'm hoping this will work out less than 0.5A, but
I've ordered a Kill-A-Watt adapter so I can get an accurate idea as to how
much it draws.

If its too high a draw, I'll have to look into getting a 90W PSU from
somewhere.

Hopefully another IP and switch port wouldn't be too expensive.
