A note of caution, the uZeus is designed to be mounted on metal rails, and while it is possible to mount them on 3d printed plastic, it's not ideal, and if you ask TipTop I'm pretty sure they will recommend against it. However, I've got a couple mounted on 3d printed plastic (albeit not in an actual case) and what I've done is put these heat sinks on them to dissipate any excess heat:
I noticed that a bit ago, so I swapped to 4MS Row 25 because it was what the person who modeled my case was using, and they added a little breakout slot to fit it on the top instead of in the main rack.
