Finally after long delaying I bought a new PC. I decided to eliminate as much cables as possible so I decided to go for wireless keyboard and mouse.
The table was made by my father (one of his few good qualities was that he was very good at doing carpentry/construction stuff, I actually always kind of wished that I could learn those things from him but on the other hand it was impossible to learn from him since you would end up feeling like a shit in less than five minutes) and it is perfect for the pc, with the under space for the cabinet; I only decided to buy a support for the screen and found this nice piece of furniture on amazon with the two drawer which helps to keep the table less messy.
I have half a mind of buying an extra support for my printer, maybe with some space below for placing printer stuff like paper and such.

I am also thinking of doing changes with the decoration stuff; I don't care particular for decorating but I feel like to, you know, make a change, getting rid of old stuff...
