Yep, seems they pretty much all do! I couldn't find a sensible case last year when putting together a new PC for my brother, who wanted it to include a CD/DVD drive. (He regularly buys CDs at 10 for £1, listens for a bit then sells them for a lot more on eBay - the demand is there.) I ended up reusing the case from an old computer of my own.

I'm sure on my own next upgrade, I'll continue to stick with my existing 20-year-old case, for the same reason.

And the drives themselves are 2-3 times the price they were at the peak of their demand (makes sense, they're almost a niche product these days).
