I have an A4000T (Amiga Technologies model), however housed in a PC AT full tower case, as I originally only bought the motherboard and audio/serial/mouse/video port cards only.
Everything is in excellent condition, especially the motherboard. My plan is to either sell it or keep it, and one day I may find a NOS original case for it, and put it in it's "natural surroundings". :-) The supplies of NOS A4000T cases have dried up, so for now I'm forced to use it in a PC case, however AT form factor of A4000T motherboard conveniently makes it perfectly fit. The look of the whole setup is completely hack-free. :-)
Make an offer if interested. :-)
