I was able to fix one of the machines!  It was a simple problem.  Apparently PCI-E video cards require XP SP2 or better.  I did not have a slipstreamed XP disk and instead of making one, I just decided to install that copy of Vista I received from PowerTogether.com.

There are a few things I like thus far and several I do not.  But it’s not fair to judge after 48 hours.  I’ll give it some time and get back to you.
