I recently bought a new motherboard for myself and thought I'd use my old one to build a semi-new PC for the wife. since I would be using some old parts from other machines and some new items as well, I am calling this "Frankenstein".
Specs:
New

The motherboard ready to be mounted. I put on the CPU and cooler, RAM, and sometimes cables before mounting in the case.

My tool stash seem to take on a life of its own and grows.

Cables attached to mounted board

The two drives, SSD+data

While doing cabling I discover two mobo screws I forgot to put in. One was fairly easy, but this one was a nightmare to put in. The board was a tight fit and if I removed the cooler to get to the screw I wouldn't be able to re-attach the clips for it because of there not being room for fingers to reach them. Fortunately I had a very long screwdriver to help out which I magnetized the end of to hold the screw and lower to its hole.
There is only about a half inch space between the CPU fan and the case top fan.

The screw can just be seen here

Two views of the finished wiring, fairly neat and tidy for a cheap case. It has no side window to see it though.

The job done.
