oh. almost forgot.. i found a a problem i didnt mention about the mod..mounting it to the side panel. i came up with an easy solution. after you remove the screen mesh from the side of the stacker case u gotta cut out some support material it has there for a fan..after u cut it out..u gotta find some like rubber stripping that can go over the edge of the circle..that way it wont scratch the acrylic window that would involve so much work. also to mount it..use some double sided tape..the good stuf, on both the box and the pump..and find a way to get the tubing to stay attached to the side panel as well...keeping in mind that it may all have to be removed at some point for any number of reasons.
