I built one too, but with some variations.
Legs are IKEA's vika curry with two spin-out drawers. Also features MIKAEL drawer and SIGNUM cable channel.
I've later added a ALLAK workchair aswell.
Made in Sweden :)
Step 1: Cutting the sheet
Cutting the radius and adding the locks.
Last I had to go through the diagonal cut again to make the halves fit tighter.
Step 2: Paint
This was the most time-consuming and important step.
Step 3: The rest
Nifty drawers that rotate around the legs.
Added some wheels to the pc to push it in the corner while the dvd Isn't in use.
The cables all got nicely tucked away, and the ones to the sorround system and tv is packed in a cable-hose initially made for industrial purposes.
