Sounds very similar to my setup, except I'm using a 700 MHz Optiplex  
Pentium III, run Linux, and use a different radio.

My IGate also gets quite warm in the summer (and down to about 50F in  
winter for the computer, down to probably -20F for the radio).  Not  
ideal conditions by any means, but things seem to keep working fine.

I can't say enough good things about the Optiplex.  It's been very  
stable - I did swap out the CD ROM, but I can't remember if that's  
because it failed (did I mention it's VERY dusty here?) or because I  
wanted a CD-R in it years ago.  It's not all that fast, but, heck,  
it's over 5 years old!  (besides, it's plenty fast for 1200 BPS packet)
