I've done this already...
I work in a school and so far I've found a couple of 1GB flash drives left in classrooms after someone's snapped the USB plug off while plugged in to a computer. So I gutted them, soldered short USB cables cut from dead keyboards to the pads left by the snapped-off connectors, and glued them into SD card cases. I use one of them quite frequently as it's got a bootable image of UBCD on it.
I own a couple of Microchannel PS/2s as well (a 286 and a 486) and I wouldn't hack up the reference diskettes either. You can download images and make copies but the original disk holds more retro value.
Oh, mine's the one with the MCA-16 10Base2 Ethernet adapter in the inside pocket.
