First I looked up the web for the original sizes from the DK cab. Finally, after hours (really!) of calculating, tracing, erasing and calculating and tracing again - I'm done with the side of the cabinet! The measurements of the cabinet plan I got were in inches, so I had to convert them into centimeters first.
I'm using 15mm or 5/8" thick MDF. After the time consuming procedure of calculating and tracing where all middle panels had to connect with the sidepanels I could finally began to cut them out with the jigsaw

After that I have cut every piece in the measurement that I need


When the bottom frame was installed it was time to put the casters (wheels) on. Measured out where they had to come, drilled the 4 holes (5mm) for each caster and put the bolts trough. I used bolts this time because of the weight the casters must be able to handle.
The idea of this bottom is really nice. When the cabinet is standing it rests entirely on the wooden frame. You don't see the casters because they are on the back and are about 1mm above the floor. But when you tilt the cab just a little bit backwards all the weight is left on the casters, leaving the cabinet off the ground.
