Hyperventilating - Just brought home PC 5150 in original boxes from original owner

Found on Craigslist - he was severely over-asking, but after emailing back and forth, he admitted he did it solely to weed out people who don't actually appreciate the system as a historical artifact, -'d sold it for far less.

What it includes is amazing though, and probably was worth his original asking price.

IBM PC 5150 (with original box, including shipping label with the name of the person I bought it from.) - original planar. Upgraded later to 64 KB onboard and add-in card to 512 KB.
*CUSTOM* ROM chip - by his employer of the time, that replaced onboard BASIC with an APL interpreter. Original ROM chip included.
Floppy controller with dual 360 KB full-height floppies.
IBM MDA adapter
IBM CGA adapter
Serial/parallel adapter

IBM 5151 MDA display with original box (again, with shipping label made out to him.)

IBM 5153 CGA display with original box (yup, shipping label.)

IBM Model F keyboard (yup, original box.)

Hayes 1200 baud modem (no box.)

Okidata dot matrix printer with original box.

A box of cables, manuals, and software. Including the original "green eyes" Microsoft Mouse, and Windows 1.0 original floppies and manual.

I'll get it all set up and properly photographed, but sitting waiting for my kid's football practice to end, so had to write this up.
