Inspired in early 2015 by the many conversions of old PowerPC Mac Pro cases to x86 PC's and the availability of cheap Mac Pros at a university surplus store, I decided to try and build one myself.
At the start of the project, I had several issues with existing solutions:
I set out with the goal of converting my case to fit a mATX motherboard, with as few modifications to the case as possible, using as much of the original internal hardware as possible, and using only parts I could 3D print myself.
With this in mind, I ended up with 7 printed parts:
The parts were printed on a Prusa i3 printer in white ABS. Each of the printed parts was attached to the case using 3M Yellow weatherstrip adhesive, providing a secure bond between the metal and plastic.
Overall, the project was a great Solidworks learning experience. I met all of my initial objectives, completing the project for cheaper than expected.
The finished product
2.5" SSD drive caddy
PSU tray & retaining arm. This view shows the tray vertical for clarity, and omits one retaining arm for the same reason
140mm fan bracket. This bracket attaches to hold one 140mm fan hanging vertically from the upper divider of the case
140mm -> 120mm fan bracket. This attaches to the bottom of the previous 140mm fan, and suspends a 120mm fan below it
Motherboard standoff for below the I/O panel on the board.
Motherboard standoff panel for beneath the PCI slots
Motherboard standoff panel for beneath the RAM modules
