I designed this in CAD and cut it out of pine on my Shapeoko XL. Some of the parts are 3D printed. The wood is 3/4 pine. I am going to use a 3mm piece of acrylic for the opening you see now. This was about my 4th prototype before it came out the way I wanted. Thanks to @WillAdams for helping with my Y axis issue.
If anyone is interested in the PC part… It fits a custom Supermicro workstation motherboard (hence the need for a custom case). It will have dual xeon CPU’s, 48GB of ram and a Radeon Fury vidoe card. I’ll post pictures of it finished if anyone is interested.
