Printrbot Power Tower alternative (Plexi Power Tower)

I just upgraded my Printrbot Simple Metal with a heated bed and now that it has an ugly ATX PSU attached to it I wanted a way to hide it. Printrbot sells a "Metal Power Tower" but its $60!!! This is an alternative to house the PSU out of site and also hold a reel of filament on top (will roll freely on bearing or metal rods). I plan on getting some black plexiglass to match my black Printrbot. Everything in the picture that is white I plan to print. I may need to print some more internal supports for the PSU itself, but we'll see how it goes. UPDATE: 6/6/15 - started to print parts and attach plexiglass together. Pic updated as well
