Hi Butch,

Check out the Dell Optiplex line. I'm not sure if all Optiplex models have 
a serial port, but there are some that do. It should be fine for XP, but 
Dell said linux is not supported on the Optiplex line. This doesn't mean 
that Linux won't install or work on these machines, but ymmv. John likely 
has more experience with linux on these  machines and might be able to 
provide more info...
