1U PI NAS, RACK MOUNT 2x RASPBERRY PI CM4

This is a 1U rack mount NAS case designed to hold 2x Raspberry Pi Compute Module 4 IO boards.
It will accommodate up to 4x 2.5" HDD's or SSD's.

The lid is in 2 parts, this was mainly done so they could be printed on a smaller printer whilst the CR10 Max dealt with the main case.

The SSD cages slide in and out and clip into place for easy maintenance.
Have added 2 a -12mm cage, this will allow for additional cabling room.
The cage clips are separate pieces to avoid awkward support removal.

Each end of the case has the required holes for 2x 40x10mm fans.
A fine mesh would be a good idea to limit dust.
There are grills to secure a mesh on the outside.

Cut version for smaller printers has been added.
A 2 part chassis requires a print area of at least 247 xx 163mm
Two 4mm diameter metal rods under 16mm long will be required to attach the two halves. there are holes at the front and back to take the rods, they are 0.4mm oversized, i'd suggest a generous helping of epoxy to secure the rods and chassis halves.

One consideration if using the fan grills.
As the holes in the chassis are printed vertically and the grills are printed more easily laying flat(and I used 2 different printers) the sizes haven't come out exactly the same(the models are though).
scaling the fan grill be a few % should rectify this, but depending on the printer, a test may be required.

Cut versions for smaller printers will be added soon.

Additional parts required:
4x 6.5mm hex risers (std motherboard ones)
4x M3 x 8mm countersunk machine screws to attach the lids
8x M3 x 6mm for the SSD cage clips, or they could be glued in (I screwed and glued).
Fan mesh.

One fitment issue I encountered, I used standard motherboard risers but found the screws were too large for the CM4 io, To get around this I drilled the board(there was space to do this). There may be specific risers for the Pi products but I used what I had.

Possible fitment issue depending on the chosen hardware.
I was planning to use the following sata board

But, as one of the connectors faces forward, it will stick through the front of the case.
My personal solution is to use a PCIE extension cable.

If you wish to use a method like this, let me know the hole spacing of your extension so I can add the required holes for stand offs.

Any of the logo's etc can be removed upon request.

And I'm happy to answer any questions.
