The initial and obvious answer is to make an Amiga Case (if the community could decide which Amiga case to make), and have it designed so that it can take two standard micro-ATX motherboards, and has a built in KVM switch. Finally CUSA should contract with Mike to purchase a bulk of the FPGA Arcades to preinstall in the case. They could optionally offer the unit with FPGA, x86, or both preinstalled.
This would allow all of the (mostly) Amiga purests to have a classic Amiga that runs all of the old classic software natively. It would help the FPGA Arcade project by giving a good sized guarenteed initial order. It would be realistically and entirely doable. It would allow those that want to run AmigaOS via emulation to do so as well as run x86 software.
