After seing Jeff Geerling's YouTube Video(which is embedded below), I was like "I want to do this!". Not planning on using the mini rack as my main homelab / self hosting setup, I like my 19 inch rack, but building one just for the sake of building one.
For further research, I went to his website about mini-racks: Project MINI RACK.
Deciding for the right rack
I wanted to try out a 3D-printable rack since it is the cheapest, quickest and most customizable option: I decided to go for the Modular 10"/10 inch Rack by @bwees, which is linked on Project MINI RACK.
Building the rack itself
These are all the parts needed:
This is what it looked like after putting together the two halfs of the rack:
And after putting the halfs together with the first rackmounted item:
To fit the main server inside the rack, I customized the "HP Elitedesk" rack mount STL file, since the Asus PB60 is a little bigger than the HP Elitedesk that the creator of the rack used originally.
The mount had to be screwed in on both sides, since the Asus PB60 is too big and heavy to be mounted on one side only. To achieve that I used melt-in threads:
This is what the result of the first day looks like:
I am also planning on adding a mount for the Raspberry Pi's and a patch panel.
