   If I looked through my records, I bet I could name the model.  A tiny 
box with hard disk, floppy drive, oversized CPU fan, case fan, CD 
reader, and a *90W* PSU?

   Some retailer here sold a crapload of those.  I put a bunch of them, 
the ones that didn't fry the motherboard, into mini-towers with real 
power supplies.

   In any other industry, those particular eMachines would have been a 
recall item.
