An Amiga "cube" capable of recording and playing back as if it's a virtual VCR. Hardware-based encoders/decoders, mediator (or similar) type PCI. Would it sell?
Another model would be a mini-ATX Amiga system with a black case. Kinda like a 3000 but with A/V RCA ports. Both models should have space for a modem and an ethernet port.
