Before I was able to fix my 18 month old machine I was looking at
Velocity Micro. You can get pretty much the machine you want and they seem to have a good rep (based on what I could read on the web, I don't know anybody who owns one).
ABS Computers made my current machine. They used to custom configure machines similar to the way Velocity Micro does now, but they seem to have abandoned that approach. I was happy with my machine until the recent problems and the fact that I had to take out the motherboard to gain access to the hard disk I decided to replace [img]/images/graemlins/frown.gif[/img].
