I could produce something similar at about zero cost - I have plenty of plywood, a spare Doepfer power supply, a Zeus for the base power and a lot of rails, not be mention dozens of modules not currently in use.
Alternatively I could use the new Thonk rails and Lamond side pieces and build 150HP wide. Four pairs of 150HP rails plus threaded strips and Lamond sides would be 4 * (£31 + £11 + £12 = £54) = £216.
In 104HP it would be 4 * (£21 + £9 + £12 = £42) = £168.
And in 84HP 4 * (£20 + £8 + £12 = £40) = £160.
84HP is around 17 inches, 104HP 20" and 150HP 30".
Modules are around 5¼" high and so three rows of 150 would be 16" high and 30" wide: that might look a little stumpy. I could not justify 5 rows of 150HP plus base.
There's some good information here from Stefan Burbulla.
If I start small and cheap, I can always rebuild more grandly and extravagantly later and so (subject to finding and evaluating the rails I have in stock):
- three rows of 84HP plus base;
- configuration will be a smaller version of the standard synthesizers.com cabinet, i.e. two on the slope, one upright and keyboard garage below.
The depth of the garage will have to be sufficient to house a base with suitable skiffy modules and at the same time the slope of the bottom rail will have some effect on the depth of modules it will hold.
[27 Aug] I have a location 18" high and 30" wide: the Mondrian/Rietveld desk.
