Building custom PC case, need help aligning standoffs and I/O port

Recommended Posts

Posted · Original PosterOP

Hey everyone,
I'm building myself a custom PC case out of Aluminum, and I've hit a snag.

I'm designing it in Sketchup first, and then I'm going to be sending the file to a laser cutting service to cut it out of my aluminum sheets. But I'm having quite a time finding information on the dimensions for placing my standoff holes correctly, so that they line up with where my motherboard's I/O ports will stick out the back slot of the case.

Any help would be massively appreciated. Thank you!

Is there anyway to get an accurate sketchup of a motherboard with the same form factor that you're using, overlay it onto your design to trace out the standoff holes?


Rear IO you'd probably be best using a standard rectangle cut out, and putting the IO shield in

Hopefully this should be all you need, some useful dood on reddit made this:

"Here is some advice that might have gotten lost somewhere along the way in your life. 


#1. Treat others as you would like to be treated.

#2. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt.

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.
