4U 12BAY UPGRADE v1.step

I was not satisfied with the current offering of hot swap rack mount cases on a budget, so i built this!  

The STEP files are shared so you can pull what you need from this model.  I've modelled the entire 4U case so you can insert your own components when building your rig.  

I have been running this build for over 2 years and had no issues with a 100% Unraid server uptime for the past 365 days.

Note: I used [these pieces ](https://www.amazon.ca/Cablecc-2-5inch-extension-convertor-adapter/dp/B00S5WOSOY/ref=sr_1_1?crid=1XC6XQLOPCDBA&keywords=sata+couplers&qid=1671687610&sprefix=sata+coupler%2Caps%2C172&sr=8-1) to connect the SATA drives. 

I fitted mount points for 3x 120mm fans, and this is designed to have a plexiglass window mounted in front, with air being sucked from the top and bottom vents. 

My average internal case temperature under load is 37c with this configuration.
