My first one was a 65MB (or was it 85MB?) 3.5'' parallel ATA one, and while the enclosure might have been shaped around the platter(s?) (could have been a later one, though) I don't recall the motor being distinguishable.

Whole machine (my first PC proper) was a 286, 16MHz with turbo on, possibly 1024KB of RAM (I recall setting up autoexec.bat to ask me if I needed extended or expanded memory on boot, but could've been in a later machine; pretty certain the memory was on socketed DIPs on the mainboard, not SIMMs, in any case, so it can't have been much, and 640KB was supposed to be enough, anyway), CGA, 5.25'' and possibly 3.5'' floppy drive, DOS... 4.something, I believe.

Good times.
