It’s a 5ft table top because I don’t have room for anything bigger. I recommend at least 6ft, 7ft would probably be perfect for a triple monitor setup. I also made the legs out of 4 2x4’s there kinda shitty I put this together in the last few weeks in hurry and the legs are just temporary until I order some more. The legs I made are sort of like these [link] But I made them out of wood. Also I just looked at that desk you linked on amazon I’m not sure if it’s real wood but if it’s particle board it most likely won’t hold up if your going to mount 3 monitors so if your in between getting that and the Home Depot route I would go Home Depot you’ll be able to do it it’s super easy
You'd be surprised how much weight standard table legs, like those found at IKEA, will hold. If you're truly concerned then I'd recommend something like this:
