13HDD 8SSD 4U NAS Rack

This is my DYI NAS. I reused some old 4U ATX rack case that was originally capable of holding just 4 HDDs and 3 CDroms. 
I really liked "45Drives HL15 case" so I borrowed idea nad HDD placement, and recreated simillar thing with 3d printer. 

After some cutting I ended up with open case without any idiotic metal cages. Few hour of printing and new HDD cage was created. 
In my design I didnt want to waste space and material for HDD sleds, so I designet it that way, that I use screws in HDDs and I just guide them to coresponding slots. Instead of some custom backplane, I am using simple SATA connectors that provide Data and power in one connector.  

My cas can take full size ATX board, but ideal is use of some smaller mATX boards.
In my homelab I used BKHD N100 1264 motherboard.


Please take this project as inspiration, not as finished thing that you can just print and go with. 
Each case is different, so You will have to measure and redraw it, or just copy paste and borrow whatever You need or can use.


Have fun :)
