After working on the design off and on for the last few months and getting all of my hobby materials organized in the new gaming room/rec room, I went out this week and picked up the lumber I needed and a circular saw, and this morning I measured out and marked the cuts I need to make this afternoon.
I'll update this post with pictures as I go, and when I'm done, I'll provide my schematic for anyone interested in doing something similar someday.

Finished all of my project cuts, although since I made the legs a little longer, I'll have to get another 4x4 and cut the last leg.
