Just a `simple' box, perhaps even with PC hardware, so you can reuse VGA, PS2,
... emulation? The actual emulated hardware doesn't matter much for running
e.g. Debian build daemons.
Cfr. Linux/MIPS has a qemu target, just for running MIPS:

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
