My gaming PC was a i5-3570K/16GB/RX580 so I was topping at 1080p on a 40 inch TV on medium to low quality to play a smooth game.Decided to buy a new Desktop PC to replace my 2011 PC that I've built.

Got all the wood already. List of materials for the monitor stand is here: https://www.tinkercad.com/things/0XsjhAAZ6iS
(a 2x4 is really only 1 1/2" by 3 1/2" but for the purpose of simplifying the cad measures while drawing it I've set it at 2" by 4")Inspired by this Youtuber: https://www.youtube.com/watch?v=inVjpuykfkY
