To start, given your <ahem>thrifty</ahem> Dutch nature

get a good, sturdy 2x4 about 18" long and just run 3" lag bolts through each pedal into the wide side (4" side) of the board. Whatever sticks out the other side of the board just cut off with a hack saw so as not to hurt anyone or anything with the sharp tips of those bolts.

To ensure a nice looking finished pedalboard try and get some nice flamey wood.
For the power side get a Voodoo Lab Pedal Power supply and using 10d nails secure the power supply to one end edge of the nice, flamey (or optionally, birdseye) maple 2x4 board. Consider epoxying the supply, too, to make sure it doesn't come loose from the side of the nice, flamey (or optionally, birdseye) maple 2x4 pedal board.
Finally gather up all the interconnects and bundle them together with Hefty® twist ties, that will provide the final professional touch to your <ahem>thrifty</ahem> Dutch style pedal board.
You might want to send this all to PW for his expert finishing, say, in Amber Fireglo.

Make sure he masks off the nomenclature for all the controls on each pedal, you wouldn't want to have all those pedals look tacky with the finish on them.
