Helios 4 CD case (RIPpchen)

thingiverse

If you have an old Helios 4 NAS lying around and would like to use it for backing up your optical media, this case is just for you. You can fit 2 CDROM drives and a HDD. Note: The original plan was to fit 2 HDDs, but the design turned out a bit tight so having 2 HDDs installed was never tested. Installing 1 HDD in the upper slot works well though. You can mount the 2 fans on the outside so that they blow in the air into the case and out of the front. Note: The original design mounts them inside, but i believe this is a production failure as that would blow the air out (at least with the fans i have), which would have little effect for cooling. The optional display can be mounted on the front. While it is not "as protected" as with the original design (where it is mounted behind), the advantage is that you can fully print the case and don't need to leave big holes or use seethrough material. You can use all the original screws of the Helios 4 kit, except for the CDROMs itself. There i use some M4 screws.
