Micro OptiPlex stacker / mini rack setup

I had a few micro optiplex's laying around decide to make a NAS and Linux machine out of them, figured someone else might enjoy the design, stacker does have one leg different as i used 3050 micro's and the front panel has a ledge, so orientation does matter on it, i printed everything in ABS with inner/out/inner walls, adaptive height set for quality, im using sunlu about 260*C @ bambus generic abs setting, and 166% speed (270 gave me alot of defects…. but i am running a 200w chamber heater in my p1s) the 4 drive case does require a hole cut in the top of the pc below it for sata cables (im running a m.2 to 5 port sata adapter from amazon)the back plane allows cable to run out the back for power (im using usbA to sata power adapter, and a sata power spliter to power 2 drives from one usb port)deburring and a flush head screw is required if you want to install screw on the drive trays, im using the built in pins and the tray has a good enough for me friction fit….as for thermal
