I made the desking myself and designed it; made it out of 20mm MDF and covered the top with sticky floor tiles (not conductive, great for hobbies, and also wipeable if it gets mucky).
I have 2 computers connected to one monitor and keyboard (hot-key switchable) and a number of other computers in my home for other tasks.
This pic is half of my room for "computing".

...and the other half for hobbies...

this pic shows my current N64p project in situ, with various junk; and a nice vertical storage system I got from Maplin for my various electrical components.
Big advantage being an adult; have my own house (with my wife); no kids, so I have my own playroom and so does my wife!
