I also took a look at the manual. I don't think it would have a problem 
with getting power from effectively 2 sources. Firstly, the unit is not 
intended to be powered through USB and may not have the 5+ wire 
connected on the Veris end.

Secondly, it's only DC we're looking at and any problem would be a 
difference in ground potential between the wall wart/whatever powering 
your external 5.25" case and the ground level on the USB header of your 
computer.
Worst case, you could build a long 3 connector extender to extend the 
wires from the 24 pin adapter on your computer, to the box, thus 
extending the computer's ground potential to the external box. If you 
did that, you could also run wiring to splice into the power switch, so 
the unit would work as originally intended: you can use the remote to 
power the computer on and off!  That would be 10 wires, so a chunk of 
flat cable might to the trick, provided you don't mind soldering the 
needed end connectors, all of which would be internal.

Well I don't know how many sites teksavvy has, but if you don't mind 
admitting that you live in Guelph I guess I shouldn't hold that against 
you too much, ya loser.

That's not too bad a price, considering. The Remote, BTW is the same one 
I've been using for about 4 years now, iMon Pad, so I suspect you will 
have no problems with getting it set up in lirc once you have it wired 
up. There's an lircd.conf and an lircrc on the wiki iirc.
