Yet computer cases are still ridiculously huge...

Most PC cases that I see on sale tend to be desktop towers, with an
array of internal bays.  And, thankfully, these days they face out
sideways, so you don't have to try and manoeuvre a drive out over the
top of the motherboard, between the cards, and through the cables.

no point trying to privately email me, I only get to see the messages
posted to the mailing list.
