I bought 4 shelf bracket like this https://imgur.com/a/qlYnqMQ and my plywood is 1feet and 2feet and I use it as a platform, the question is, can this 4 shelf brackets hold my 10kg for so long because my room is so small so the only option is to mount my pc on the wall, I don't have so much money to buy a pc case with mounting features in the wall, even the pc case holder I saw in amazon because my country doesn't have access to amazon the shipping tax is double the price, sorry for my english I am living in 4th world country
