My old projection tower was a cube. My projector sat on the top, and my computer said in the bottom.
It was a pretty good solution, worked fine in California, because, well, the weather is better there.
It fell apart last week, so I had to build a new one.
The front, facing the screen 
The back.
That’s what I have so far. I still need to paint it and install some equipment, and make a small stand to hold it up.
Ok, painted up and pressed into service. I need to build the base, and mount the equipment inside.
I built the stand today. Reused a lot of the old stand. It’s ok, needs some paint for stability.
Very nice! Simple. Functional. ‘Looks to be well executed. What else does it need? Oh yeah, paint…. for stability. That always works….
Paint as a structural component.
