Actually, you are correct about the 1820A, I made a typographical 
mistake... I do have an 1820A, and the reason I chose that over the 
standard 1820 was the onboard processor.  Sorry about the confusion.

Good luck with your set, I'm already very impressed with the performance 
of it (for the price), and I do plan on upgrading to a newer board/CPU one 
of these days.  My problem is that I can't just throw something out if it 
still works, so I try to make use of it until it dies, and then I can 
justify buying something new (however, by the time this board dies, I'll 
most likely have inherited some other slightly newer still working board 
without 64-bit PCI, and I'll be forced to use that until it dies... :) ). 
That's the primary reason I went with this board, that it would work in 
what I already have, and should work for a time to come with whatever I do 
end up getting.

I did splurge on a new Dual Xeon setup which will be for video encoding, 
but I have a SCSI subsystem for that machine, and I needed the horsepower.
