As you can see from my previous 2 posts to the sub, I had 2 issues:

1. My desk couldn't hold my PC because it was too shallow and not wide enough.
2. My desk was a bit shaky and was on uneven ground.

One commenter suggested I bolt my desk to the wall and it seemed like a good idea. Though I don't plan to use my current desk as, it's quite thin, short and looks a bit weird. So I've decided to attach a sort of desk-top to some triangular brackets and bolt them to my wall like [this] (https://i.ytimg.com/vi/lTxQ59GE91Q/maxresdefault.jpg).My desk has a limit of 47cm deep, It can up to 140cm long and must be able to hold my mid-tower PC.My home walls are also concrete, so I don't have to locate studs or anything like that.It seems to fix all my problems but I have a few questions, as to how to go about this:

1. Is this possible to do this?

If so:

1. Where would I be able to find a desk/table top that meet my size and strength requirements? (Would I have to get it cut by a professional or can I find one online)
2. Which triangular bracket should I use?

Here are some more images to reference what I'm trying to achieve:https://www.youtube.com/watch?v=AluMwKyfwawhttp://upsite.me/diy-wall-mount-desk/diy-wall-mount-desk-oak-wall-mounted-desk-diy-wall-mount-computer-desk/http://www.instructables.com/id/Floating-Desk-Build/
