Corner construction

I got the 3/8" Tempered glass and the 3/4" Pipe for free. I cut the pipe to the length I needed and threaded it.
To hold the glass i welded flanges to a custom corner bracket. The threaded rod and split ring hangers pull the corners together grabbing the glass firmly.
For the computer tower (cool mini itx build I made) I bent a piece of aluminium to sit as a tray supported from the main legs.
