Lee, I know the stuff, I've used it to line the toilet cubicle in my workshop :) Personally I think it's too fragile but then I'm used to industrial stuff and like to make things solid and bullet proof.

Chaz pictures of the PCs attached:

Processor Intel(R) Pentium(R) D CPU 2.80GHz, 2793 Mhz, 2 Core(s), 2 Logical Processor(s)

Most have had the HDD removed but I've found a box of suitable HDD's !!!! Some have DVD / CD players, at least one has a floppy disk play - all are modular so you can make a specific one from bits of the others.

All have a parallel and serial port so good for MACH3
