Maybe next weekend (long weekend, but not actually celebrating Christmas until Monday,) I'll tear down my 128K again and get better pictures than when I first got it. The only non-launch-stock component is the logic board; which was replaced with a 512K model at some point. I have since acquired an original launch-stock 128K board, but it's dead. I also have an original launch-time 400K external floppy drive (completely jammed mechanism, unfortunately,) and mouse (broken vertical interrupter-wheel, so I use a newer Mac Plus-era mouse,) and serial cable; along with an HD20. I can have either a very nice launch-time LOOKING system (broken drive and mouse,) or a usable system (newer 800K external drive, newer Plus-era mouse, HD20.)

I also have a dead HD20 that I'll probably convert to an HDxxSC one of these days by swapping the guts of a no-name SCSI drive case in. (The controller on it appears to work, as it attempts to mount, and is identified by the test utility; it just doesn't pass the test, nor can it be formatted, so I'm assuming it's the drive itself that's bad.)
