Drew these up earlier and thought you guys might be interested in taking a look.
This is just some preliminary thoughts "put to paper" as it were, nothings final, and i know there are room for improvements.

Here's a view of the front, this cabinet is designed to look like a guitar amp.
The back, where the head of a real guitar amp would be, houses a carbon filter, seen on the left; which is operated by a fan (represented by the box with the circle coming out of it, on the left

) And the reservior, of which the pump sits atop, so in the event of a power failure, the growing chamber will not be flooded.

This view shows the feeding tube, which three plants would sit in, over that hangs a ScrOG-style screen, and finally four fluorescent tubes lighting the box.
The front "door" would be covered in a cloth material, to appear to be a real guitar amp.
