I'd buy it buy I already have a similar setup and the USD is sucking wind.
I would think someone would have snapped it up by now with that ARM controller.
I guess people don't realize how nice the Minimig 1.1 with ARM is running at 50mhz in turbo mode getting 2 - 2.5 mb/sec off the hardfile. Otherwise I think you get like 250K/sec which is pretty lame. And its not as if those ARM controllers grow on trees

is your Amiga 500 inspired case for the Minimig 1.1 or new FPGA Replay?
what makes your case more A500 inspired than say A1200? The reason I ask is just I do like the A1200's case a little more...
