my Cabinet (rebuild 2017)

Cabinet width is 1 m (height about 50cm), simply 'cause it is easier to build. Most wodden boards you can buy of the shelf are 1m by default and the Aluminium-Rails are too, so it saves a lot of woodwork ;)
Rails are now Aluminium from Gie-Tech

Wood is simply spruce ... because it's cheap and it looks nice. You can take whatever wood pleases you.
Important Hint: You can take whatever material suits you .. this is DIY, so you can do whatever you want and choose the sizes you want ... the main-functionality of a cabinet is ... holding the panels .. looks weird if those are straggling loosely on the kitchentable .. but will work too ..  (hurray)
I added 2 and a half rows in a self-invented panel-size (18cm*5cm) to get more modules into my cab.

Why did I decide to get a non-standard format??
Simply because it is DIY and because I can 😉 .... and to me, this kinda 4U format suited me best.
I never planed to add any non-diy modules, so, for me it works perfectly.
Plus ... if the cab is 1m in width, I can add exactly 20 units to it, without filling some empty space.
Panels are made from 2mm Alu-Dibond now. This material is easier to cut and drill than pure aluminium panels and costs are not that high in total. The stability of these panels is absolutely enough for 4U and 5U modules.
I added 3 Powersupplies in total.
All +/-15 Volt.
2 * Meanwell PSUs (in the front - PD2515) for all standard modules that do not need to be fed with 100% pure symetrical power, and one Velleman K8042 with a nice big HS4003.
For the Vellman I added bigger el. condensators (C1 and C2) and a torodial transformer
RINGKERNTRAFO 2 x 18 V 50 VA. (Kit plus ring core is about 50 €)

Why different PSUs?
Simple, you can power most modules with the meanwells, and they are cheap (~15 €).
These are open-frame PSUs, wich means .. there might be some minor fluctuations (0.1 Volt or less) to the voltage from time to time (works with LFO's, VCA, EG, most VCF's, GATE Generators, .......).
BUT if you have a look at the schematics of most VCO's, you will see, that the coarse and fine potentiometers are directly connected to the powerrails. This means (depending on the parts) minor fluctuations in the voltage have the same effect as if you play with the coarse and fine potentiometer knobs. And you really do not want that while playing.
I will also power the CV breakouts and other voltage generators that are used for the VCOs from the Velleman PSU.
HINT 1: If you connect a torodial to the Vellman PSU, you need to connect the mass output (between the +15v and -15v Outputs) directly to the mass of your power connection.
HINT 2: If you connect both +15V and both -15V of the two Meanwell to the same powerdistributionboard, you will end up with 2A in total instead of 2 times 1A ;)
Do NOT connect the symetrical too, we want to keep this seperate for better stability.
And this is how it looks if some blank panels are added.
Total costs are around 200-250 Euros (incl. Rails, faceplates and powersupply).
The Aluminium-Rails cost the most of it. If this is too much you can start with simple wooden rails and attach the modules directly to them.
How I do my panels: will come soon
