I was going to suggest something out of the Alix line for a support PC, 
since they are low power (again, in comparison to a 100 - 300 W desktop 
computer) and give one access to the tools needed to remotely control a 
TNC (however, one would need to add a serial port, probably using USB). 

2.4GHz or 5GHz at the site would likely be a hit or miss proposition 
unless a directional antenna is used and some power. 

When you're dealing with a site that has line-of-sight to over 50 miles 
away, there's a lot of noise that can be picked up. 

I assume that this digi will be shared with a repeater that has a very 
good antenna (DB-224/8/Super Stationmaster). =)
