This inexpensive triple monitor stand is a sturdy and attractive mounting solution for your desk. All you need is basic carpentry skills to make your own version.
Reddit user LukyNumbrKevin shared the detailed parts list and an image walkthrough for this project. The total cost for his Nvidia Surround monitor setup -- including the cost of the monitors -- is a little over $200.
After seeing monitor mounts for more than $200, he used Google Sketchup to design his own.
You can use pipes to create a DIY triple-monitor stand, but if you prefer a wood base or working with wood better, follow Kevin's lead.
