Yes, but considering you weren't supposed to replace this fuse (it was
inside a case seccured with tamperproof screws, did IBM really think this
mattered?

I have a commercial AT clone (made by a company called AES) which has an
open-PCB SMPSU at one side. No cover over it at all. No, I don't like
this design at all.

What's wrong with them. I seem to remember tracing out schematics of the
PSUs in my PCs, and I didn't think they were that odd. They're better
than those infernal Boschert 2-stage ones....
