The routing and design rules for that will be fun. I recommend watching the Altium high speed board design videos and closely follow the Intel design specs if you want it to work. Trace length/resistance matters.

Another idea for a deeper HDD sound -- a solenoid. It could be mounted to the chassis so it gets the similar vibration to a normal HDD. See the clunker keyboard as an example: https://mechwild.com/product/clunker/ What about a cell phone clicker? Like the thing apple used to make you think you …

Don't know why you'd cut up the card's cooler when you can just put new capacitors on the board with the legs folded over at a 90-deg angle.. When I can't fit my car in the garage because my son put his toys in my parking spot, I don't cut a hole through the garage door so it closes.

The case is missing shielding for electromatic compatibility. https://en.wikipedia.org/wiki/Electromagnetic_compatibility Back in the day, this would have been higly illegal due to the possibility of causing radio interference, RFI/TVI. Remember that show cases were forbidden for regular use, as …

No mount patterns. They can easily be added though. I am just going to superglue the standoff STL's into place. I have used that method before in other cases instead of drilling/tapping, and it works well. The U-shape cover is probably only big enough for a SBC backplane though. The drive bays are …

It fits perfect, minus a few screw hole offsets. I'll correct those and then upload the Sketchup/STL files. edit: attached to post #2 of this thread. Filename PXL_20220928_131148386.jpg File size 478.7 KiB Views 475 views

There are easily a dozen or more ways to make covers/lids for this. It's best just to try out something and see how it goes. With the U-design I'm printing right now, it is the motherboard side, top and bottom. Then all that is needed is a single sheet of clear plexi for the case window, and a rear …

I drew up a quick u-shape case that mounts to the cube mounts.. we'll see how it fits once it is done printing. I already realized one slight screw up in the mounting hole positions, but they can just be filed easily. I'll fix them in the Sketchup/STL file once I see how everything fits. Should be …
