Be reasonable, the C= ones had a different looking front fascia than the AT models, otherwise they were identical. Yes this makes them rare, but so what? There are good reasons to own an A4000T: plenty of space for drives (5 external bays & 1 internal one), coin battery with a battery connector for replaceable AT-style batteries, large roomy case (a standard AT case from Enlight, a company still in the business), a standard AT PSU, extra ports in back for "goodies" -- USB ports & Indivision AGA DVI connectors, plenty of Z3 slots and an extra fan for cooling. They are easy to open and work on, able to leap tall buildings in a single bound (oops, that may have been Superman), and more were sold in the states than in Europe.
