IIRC one the XT or AT class machines that Zenith made was built this way (backplane instead of motherboard and CPU and memory on a card). Also A LOT of the industrial PC were/have been/are built that way. In fact, I'd say that nearly all the rack mount PCs that I've seen are built that way. Texas Micro is one such manufacturer. You can go to their web site and see all the stuff that they have.
I'm currently playing with a rack mount XT that I just picked up that's built this way. It has a tiny 8 slot backplane with 8 bit only ISA slots. The CPU (NEC V-20), memory, keyboard interface are on a 1/4 length card. The IO card is also a 1/4 length. Another 1/4 length card is a National Instruments GP-IB controller and another emulates two floppy drives in Flash ROM. Best of all is that it has a 5" gas plasma screen on the front of the case and it connects to a small video card. Most of the cards in this one are made by Tempustech <
