Pi NAS, Rack mount 1U Raspberry Pi CM4 NAS

cults3d

This is a 1U rack mount NAS case designed for a Raspberry Pi Compute Module 4 IO board. 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 -12mm cages, 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. There are three 1 part Chassis files; V3.1 has countersunk fan mount holes, if you do not want to use the additional grills. V3.2 fan mount holes are not countersunk, this is for use with the grills to hold a fine mesh. V3.2-SATA Card Mount Holes: as the name suggests, this has mounting holes for the SATA card I have used.(link down below). 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 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. A 4 part requires a print area of 187 x 161mm (will fit on a Creality Ender 3 V2) Six 4mm diameter metal rods under 16mm long will be required to attach the 4 pieces, as above there are 0.4mm oversized holes in each part to accept the rod and epoxy. 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. Fan mesh. 2x 4mm x >16mm metal rods (for the 2 part print only) 6x 4mm x >16mm metal rods (for the 4 part print only) I am still awaiting delivery of a few parts to confirm proper fitment. Should any issues be found I will correct and upload fixed files. 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 boardhttps://thepihut.com/products/pci-e-to-4-channel-sata-3-0-adapter-for-cm4-io-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. Like thishttps://www.amazon.co.uk/gp/product/B09K7Q8HDB/ref=ox_sc_act_title_3?smid=AOX8JCM0WK8NW&psc=1 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.
