Different types of Xbox kits?

Hello! I was wondering if there was some information / list of all the different types of Xbox DevKits discovered so far? I'm only aware of the Alpha tower, Xbox Debug Kit and DVT4, not able to find too much info on their innerworkings.

Thank You!

 

Then there are DVT3 kits, both dev and debug (same case, debug lacking the extra ports). Lots of variations of internal kits, DVT2s, DVT6s, meaningless stuff really. Lots of different debug variations too, some with text, some without. Some with the different logos, some without. Black kits. Oddballs like the "Special Edition" labeled one.
