Yes I had a PC XT with its 10MB hard disk and a single 360 KB floppy and 128KB RAM which I later expanded to 640 KB by clearing the through hole plated holes on the circuit board, inserting sockets and inserting the chips. I later bought a PCAT clone chassis with just the motherboard with the 80286 processor running at 6 MHz and a 5.25” 1.2 MB floppy drive from a little known company in Austin called Dell! Started me on a whole journey of building machines until I built my last one in 2017! Interesting days.
