I decided to do a 2nd prototype. Since the last PC prototype ended up as my permanent shop computer I decided to 2nd one and see if I could do one with a little less emphasis on the legs.
This one is built 100% out of solid Poplar. I wanted to do a test piece out of Poplar because I had tons of it left over from a household project. My main goal hear was to come up with a system for attaching the top, Base, and bottom in a way that would be kind to wood expansion and easy to take down.
The top and botom have a 3/8" rabbit that sits in the center (base)section. This rabbit lets the top move 1/4" in all directions.
A small threaded brass insert allows me to tie a 1/8" threaded rod to the top, then through the base and a hole in the top. The small angled legs go over top of the rod and a small nut holds it all together.
Things to change in the next pass:
-------------------------------------------------
I did internal 4mm dominos on each miter joint on the base. Even these were a little too large for the 3/4" walls. I had one blowout during assembly. So thing I will do something diffent on the next build.
I am using a Zoltac 9300 Mini ITX board and a micro ATX power supply. With a wireless keyboard these make the perfect meda machine. As a matter of fact this one is going in my home theater as is. My next build will be for a larger system. It will house a I7 and monster gtx295 video as well as removable hard drive and blueray burner. This means a larger case and more creative cooling.
