All 9/03 MB's came with version 7 DB's. The rev 5 must have been placed in the box along the way... Rev 7's were standard on 9/03's. FYI: 9/03 systems were manufactured in Hong Kong and in West Chester PA.
The only differences are the West Chester builds had red writing for the serial number and white protective plastic for the mother and daughter board, while the HK units used clear plastic. Otherwise they were pretty much identical...
IMHO, the West Chester Builds failed less and seemed to take a bit more abuse, at least this is in my case. The 3k is a great box, but they can be very troublesome if they weren't taken great care of. Unfortunately, 3k's tend to be more twitchy then the 2000 and 4000, and fail easier.
I still love them, funny that they are the most expensive desktop to purchase, when they are so picky and require the most work. At least they did have a high build quality with good stuff in them.
Enjoy....
