Need new computer

[James]

I'm trying to install Linux on an old NEC, but having many problems with
the computer once Linux is installed.  I've set up and run a Linux server
before, and I know that the problem is with the computer, not the user  ;)

What I am wondering is, where in Eugene would be a good place to buy a
decent used or new low-end computer that would be sufficient enough to run
a web server on?  I don't want to spend more than $400 on something new.

Thanks for any suggestions.
