I don't really care about somehow covering up that I'm running WinUAE in XP, I wouldn't have any way of concealing that I'm using a PC keyboard anyway
And where would I hide the beige metal box with the noisy PSU fan?
I'm not towering any Amiga and adding a PC keyboard and LCD monitor to it either, if a visitor has questions I'll proudly explain why I have an Amiga on my work desk.
Then again, the idea of having a PC for the sole purpose of using it as an Amiga has its merit. But I'd rather use Amiga on loved and cared for hardware than deprecated hardware.
