On monitor mounts, no less.
As JT mentioned, please don't do this. It literally adds nothing to the thread. Like, it contributes even less than "me too" and in general, it's not a very good schtick.
Also, as a general rule, I approve significantly of what's going to end up being 68k Mac blades.
I would approve significantly of a version of this based on Performa 630/6200/6400 boards, especially if you can figure out how to make the units share an optical drive without restarting or shutting down every system in the enclosure, and of course KVM into a well-integrated enclosure is always a plus.
Something like the tower version of this: http://www.fujitsu.com/fts/products/computing/servers/primergy/blades/bx400/ -- In fact, if you put it on castors, the whole thing becomes even better.
