There's no real need to use plexiglass. Wood does the trick just as neatly. The positive pressure however is a nice touch, in combination with good air filtering this will keep most of the dust out.
As for keyboards etc.; be prepared to replace them. several 8 keyboards last a lot longer than an industrial strengthened 80 keyboard.
