I have one like it. It has a plastic lid though.
I also replaced the faucets with Forward Sealing Sharron's...
Of course this option gave me 2 other faucets that I could use elsewhere, like on a keezer collar.
If you are using on a Sanyo the directions tell you to cut to the first set of ribs under the cover.
I felt this area was too small and the tower tilted a bit when pulled (had movement).
I went out to the next set of ribs which required a larger piece of wood, but gave it more stability.
