macintosh G5 protective case

[hooklahoma]

At work I have 6 very expensive macs that do the imaging in our lab. We don't have enough space to put the g5s on the desktop so the floor will have to do. Does anyone know of a vendor that has the old style case holders that will fit a mac. I dont want Joe janitor bashing his broom into my 15,000 dollar imaging system.

thanks
