I've got a Core P1 case that I'm looking to wall mount the pc above the monitor (full build) i'm looking at TV wall mounts obv they hold up to a certain weight, so roughly what does a full build PC weigh???
Why look at TV wall mounts to mount it?
You have to remember TV wall mounts are designed and tested to hold that weight 2 inches from the wall.
You'll likely need to use proper brackets and wood of your choosing.
