Hi there, I scanned Craigslist religiously for my area (Bay of San Fran) and eventually found this unit for $100. Its 72" tall and 14" deep and 27" wide. As you can see from the pic it has support rods 1/2 way up as well as four other vertical rods for the shelving. The shelving supports are adjustable in height.
I just started mod'ing the unit.
Step 1: Picked up a pair of 4" and 2" L brackets from Ace Hardware, painted them white, painted screws white and then used the larger ones to anchor the top of the cabinet to the wall. The two smaller ones were used on each side of the base to stabilize the unit ... it is San Fran after all!
Step 2: I used some white silicone glue to fill in the gaps between the glass plates and the wooden base and top. Masked off the glass and bases and then inject the sealer into the gaps and then remove the tape; nice a clean.
Step 3: Used grey 1/4 and 1/8" weather strip foam to seal the edges of the door which is in the right side of the cabinet.
Step 4: Added clear silicone bumpers to each of the shelf supports so they don't clank against the glass.
Step 5: I was concerned about the glass shelves sitting on the metal supports as it was quite smooth and slippery.
So I got some 3/8 tygon tubing and cut pieces to create sleeves for each support.
So still have lots more to do, not the least of which is lighting. Cannot find any LED channel material that will attach to glass without using double sided tape so might have to 3D print some clips to attach to the glass shelves.
