Custom home server

To host this portfolio website, store my files, host product licenses for eirspace, run a VPN and various game servers I needed a simple server. I ended up reusing computer parts I had laying around and incredibly cheap decommissioned server drives to get it up and running as cheaply as possible. Using a normal tower PC case was also out of the question so I designed a case to be 3D printed.

The top section is optional as it just houses 4 extra drive bays bringing the total up to 7, the power button and extra USB ports none of which is necessary right now. Nestled between the sections also lies a fan that will draw air from between the top 4 drives and blow it over the motherboard.

The server as of right now is as  I have designed a lower profile top section without the drives and only incorporating the central fan and power button mount.

This is a much needed upgrade as the drives often exceeded 45°C beforehand which is said to greatly reduce their reliability. The drives now rarely exceed 35°C. An ARM based offsite backup to this server is under development to keep files safe in the event of total failure of this one.

To save cost I am once again using spare parts I have lying around. This time though I do not need the power or compatibility of x86 and definitely want the power savings of arm. I am building a server based on the old Raspberry Pi 3 and some cheap laptop hard drives as the Pi 3 is a hugely popular single board computer I can save time and download someone else's design. 
I ended up going with this design https://www.printables.com/model/149789-pinas-the-raspberry-pi-nas with some slight modifications.

This server syncs a backup of all the data on the main server over Rsync every night and runs in a separate location 100's of km away.
