Silverstone CS380 5 Drives HDD Cage

Print without the supports upright in PETG or ABS/ASA, to reduce warping reduce cooling to minimum. I used 15% triangle infill with no cooling for 50 layers, max at 75, but still only 10%. For bridges use no more than 25% cooling boost.

The original 8 drives cage needs to be removed, all screws and at least 5 HDD caddies need to be retained.
I used this backplane, Jonsbo N1/N2 NAS Case 5 SATA backplane should also work.
The backplane was installed using fan screws, and the bottom of the cage was installed re-using some of the screws from the original cage.
If a card which takes full 3 slots is being installed then the top may need a bit of shaving, I designed it around RTX 3090 taking 2.7 slot, so the back of the card sits on the cage taking the strain of the PCIe slot.
There is also no backplane version.

I also attached vented 3.5" Bay Blanking Plate which will be needed to cover 3 top bays, depending on the setup. This one needs supports for the latches. They are pretty tight fit, once installed they will definitely stay in place.
