The one thing I haven't had much luck on is finding metal cases that support expansion to support one or two or three HATs, WITH a fan.  To me, something like this really needs a side-draft mounted fan to get the air movement to the CPU.  I've found these but not using ideally ferric metals (steel... not aluminum or plastic).

We have found that placing the board and any HATs in a faraday cage (metal case) solves on board problems.
