content: I just found out about a special kind of motherboard "case".https://www.ebay.ca/itm/DIY-Mini-ATX-Bracket-Open-Aluminum-Alloy-Frame-ATX-Motherboard-PC-Computer-Case/192883113943?hash=item2ce8babfd7:g:23sAAOSwevtcqW7tIt's just a bunch of 20 x 20 aluminum "rexroth" style extrusions with some extra hardware. The link shows a 12 inch by 8 inch form factor. I want a bigger one. I found the extrusions and endcaps by themselves, but I've looked for the extra hardware bits that let you assemble a "case".Does anyone know where I can buy the feet, motherboard standoffs, and whatever gizmo holds the cross members to the main extrusions?I guess I need specific names of these parts that will fit in the grooves of the extrusion.I've looked at the "see other items from the same seller" for a bunch of these and come up empty.Anyone have any leads?

content: Yeah thanks, I guess I should have cast a wider net. I didn't think that 20mm extrusions were rigid enough for a 3D printer so I never looked.I found thishttp://catalogs.8020.net/80-20-Inc-University-Booklet/20/#but I still need to find feet and those long screws that hold the cards in place.

content: I'm building my EPYC casethat eventually become 'closed' rather as OP's link.The standoff is pairing with an insertion nut keep MB and cards in place and aligned.The few pieces a rubber slot cover been cut off and fitted into slots, hopefully avoid any potential vibration from PSU.Still in progress and need to decide on a cover material - very likely a perforated mesh except a polycarbonate panel on back-side.

content: I now know that 10 and 15 means 1.0 and 1.5 inches, and 2020 is 20mm. So I can order all kinds of brackets and thingies on ebay but it gets expensive in a hurry, more than the value of the electronics I planned on plugging there.Here's the feet I'd orderhttps://www.ebay.ca/itm/4pcs-20x10mm-Sliver-Aluminum-HIFI-feet-Chassis-Headphone-Amplifier-Speaker-DIY/192582619884
