Having just pulled the trigger on the first half on my planned Eyefinity setup I caught the triple monitor stand bug. After the cost of three new screens and knowing a 5870 was in my future I decided to go the DIY route. Inspired by this guy
(who was inspired by this guy
) I knew that plumbing was the natural choice for the structure but I was less happy with how they actually mounted the screens to the pipe. I had the idea that an electrical plate cover might be just about the right size for a VESA mount and after a trip to Home Depot I confirmed that it was basically perfect for a 100mmx100mm setup like my new monitors have. After I had a plate I could mount to my monitors I needed something I could attach to the plate so I could hang them from the pipe, after a little looking I decided that #1 conduit hanger fittings would be perfect. The one other thing I did different was offset my T connector so I could use the same hanging method for the middle screen as the left and right.
Here's the total shopping list:
3x 3/4" x 12" threaded pipe
1x 3/4" x 10" threaded pipe
1x 3/4" x 8" threaded pipe
2x 3/4" 45° angles
1x 3/4" T connector
1x 3/4" 4 bolt flange
3x quad outlet electrical plate covers
3x #1 conduit hangers
4x 1/4-20 2" bolts w/ nuts
3x 1/4-20 1/2" bolts w/ nuts
12x 4mm-0.7 8mm machine screws (VESA standard adjusted for custom length requirement)
Grand total - $40
Assembly took less time than shopping (literally). After cleaning the pipe I arranged them as you can see in the pictures. The only thing I really had to "fabricate" was the imitation VESA brackets, I drilled one hole in the center for the 1/2" bolt and conduit hanger as well as one in each corner for the 4mm screws the monitor will hang from (I know the pics are a little ugly but the holes are over-sized enough that I have some wiggle room). That's really it, the pictures speak for themselves from there...
This stand should hold three 21.5" screens with a near perfect fit but I won't know for sure until Thursday when mine show up! Will update this thread then.
