Thanks anyway, but I've decided to install a LS-120 drive in my existing system to read and write 3.5" floppies.

Well, I'm not a game player, so that doesn't affect me. Perhaps there's a socket 939 board that fits the description, then.
I have a socket 478 P4 mATX board from IBM that supports 2 floppies, but it's utter garbage otherwise. Uses SDRAM, not DDR and a slow P4...
Thanks for the offer, but I need the board to be ITX or DTX; It's going to live inside an unmodified IBM 5150 chassis and mATX won't fit in the motherboard area.
Are you sure it won't fit? I looked at a couple of pictures and the 5150 has five slots on the back, which is more than enough for a MicroATX board. Though I'm not sure how you'd mount it since there is no space for the rear I/O area unless you mounted the board sideways or something.
Also keep in mind that not all MicroATX boards are the same dimensions. Some are what I like to call "2/3 MicroATX" where the front part of the board is cut down an inch or two like this one:

These types of boards are very small and cram into confined spaces pretty good. I managed to stuff a board about this same dimension into a Compaq iPaq and it has far less room than a 5150 does, a 5150 is like a warehouse in comparison.
A 5150 motherboard roughly corresponds in size to the "Baby AT" form factor that was popular before ATX cases came into the picture; rougly 330×216 mm.
A microATX (typical) is about 244×244 mm, but some are as small as 171x171mm, or just a silly milimeter larger than a mini ITX.
Regardless, the holes will be in the wrong places and the expansion slot positions won't match modern spacings. A PC XT case could well accomodate any standard Baby AT board, and has the correct slot spacing. I used to run a 486 in one with no particular issues.
Now, WTX boards are really impressive...
I am sure others and myself would love to see pictures of the end result!
