I think that slot is probably designed for SSDs instead of HDDs. SSDs are significantly slimmer and would fit there without fouling the side panel. From the promotional material I can see of your case, it looks like it comes with a cage designed to hold 3.5" HDDs - to fit this drive properly you’ll need a caddy to adapt it to fit that, and install it into there instead.

Well done, that’s quite a commitment. I watched a lot of trek as it aired, but I’ve still not quite seen all of TOS or ENT - and I’ve skipped out on the Kelvin films after 2009.

The most surprising one I think has been Prodigy; I didn’t expect it to be as compelling as it ended up being.
