I plan to wrap the whole thing in insulation. Right now the HD is the loudest thing in my case, and I really hate the high pitched whine it makes.
As for removeable top, I don't see any need. The inside will be entirely open, so its going to be tough to clog a chamber 3+inches wide.
As for the barbs, threading the copper is not out of the question, but I'd have to borrow the tools to do it. Would drilling the holes and using a lot of epoxy or JBWeld be a bad idea?
