Do you mean take the board out of this case and put it in another, bigger one?
I actually do have a larger, older tower that I fished out of the trash. Came with a 56k modem! But I don’t know if they would fit together. I also don’t notice anywhere particularly suitable to holding a bunch of storage; I guess I would have to buy (or make?) some pieces.
Here is the board configuration for the Small Form Factor:
I did try using #9 and #10 for storage and I seem to recall it kind of worked but didn’t totally work but not sure of the details. But hey, at least I can use a CD drive and a floppy drive at the same time!
