cases are expensive

Post by alex82 » Fri Jan 09, 2009 6:32 am

Ok, the stuff from doepfer is often cheap, but that you can't say for the cases. I'm always annoyed when i plan a system, and because of eurorack has so little space, you need often 1 Rack more, and thats makes it expensive.

But why? In this cases is only a power-suply..

Ok this low cost cases are a little cheaper and i often consider about swapping to these. http://www.doepfer.de/home_d.htm
But i ask me always why there are that cheaper ? Is there maybe worse electronic inside than in the normal 6er cases?

And are there maybe other disadvantages?

Maybe more intersperse because of the wooden case?

One disadvantage to the low cost cases is that they can not be mounted in a rack or case... making it harder to take out on gigs, or position well in a studio. They pretty much just have to sit on something, and can not be *safely* stacked on top of each other from what I can tell.

The cost of cases are killing me as well. There are so many more modules I'd like to get, but the cost of racks to put them in are just too damn much. Module makers would sell a lot more modules if someone would make a good rack-mountable case with power supply for cheap... I think this is what Plan B realized, and is trying to accomplish with their upcoming cases. I am definitely keeping my eye on them and waiting to see the final prices.

Every part of a case can be sourced separately. Part of what you are paying for, when buying a finished solution, is the supplier's time in:
  • Sourcing all of the parts from a variety of purveyors
    Negotiating & Buying them at a decent price
    Shipping them & Storing them at their place
    The design of the system
    The assembly of said case/system
    Plus, there has to be a profit in there somewhere or it is just a big ball-ache for nothing.
I decided to source a Schroff case and then bought an Analogue Systems RS-15 back panel. It is not the cheapest solution, but one could easily look for a proper power supply and/or transformer and rig something up.

Here are photos of my ASys/Schroff rack: Big Alâ„¢ Schroff/ASys Mutant
Perhaps some inspiration in there.

Also, Mr. DragonsLair; here on Muff Wiggler United International Circuit-Lovers Pr0n Forumâ„¢, makes some cool Frac & Euro cases. His power supplies accommodate both kinds of voltages: Country & Western <--- Blues Brother reference

Wood + Screws = case.

Less thinking more synthing.

I would love fancy cases but they are too damn pricey, now and forever.

great thread!

I switched modular formats a few months ago to Euro, i got a doepfer monster base case and it was not only filled in a week, but overflowing with modules i "need".
My last system was a 1/4 system that consisted of a main cab and 2 seq cabs. I'm taking my old sequencer cabs and converting them over to Euro...i bought a few used powerone PS's and mounting rails..the rails/inserts wont be here for a few more weeks though...
I really like what you did with the perf board for distribution, i never thought of that, i'm going to see if Mouser carries perf board that size.
Any suggestions you have are appreciated, i'd rather take advice from someone who has already completed this type of project than make any mistakes.
thanks
Josh

A 6U Schroff rack costs $98 USD factory direct from Schroff US. They get cheaper as quantity goes up. Even when you factor in the cost of the PSU and bus components (which get cheaper in quantity as well) $530 still seems a bit steep. I think the cases should be cheaper. More cases sold = more modules sold.

But that's only my opinion and I'm sure if I was a manufacturer and knew how much time and effort went into these things I'd be able to justify the price too.

Yeah, but keep in mind that a case is a SKU (product in the inventory) like anything else & there has to be some kind of mark-up in order to even make the PITA worth it. More cases sold = more money too. Just like modules.

Of course there should be a mark-up I'm just saying that maybe it shouldn't be so high and that the loss of profit on the case could be made up for by more module sales.

Unfortunately I understand what a SKU is...I hear that word over and over and over again all day long from the marketing drones here at work. :lol:

great thread indeed. thanks for the examples of very viable DIY solutions.

i have a related question/relevation...
i now own a 6U RS15 and have another G6 on the way (thanks drew!). Each case has a 1200mA PSU. According to the modular planner, I'm only using 832mA with all 4 rows filled...meaning I have plenty of leftover power, right?

Couldn't I add at least another two rows with a schroff rack ($98 ), and bus power out of the back of one case into the schroff, add some bus boards, and be on my way? Maybe a ribbon cable>panel mount DIN connectors>ribbon>planB model 1.

Am I missing something?

here's an idea, too:

Wood plus the threaded rails you put inside the euro rails - screw those rails directly onto the wood, and you can mount away.

It won't be as slick, but you'll save 10-15 euros per 3U space, and once they're mounted no-one will know.

I can't recommend screwing modules directly into wood, those holes will be widened faster than (insert gross porn reference here - looking at you, Kent and John!)

It sounds like you'll be right. Just chain bus boards, keeping aware of total current consumption per chain.

+1 on the schroff case.
others from Rittal, Elma, Vero.
Nice to see a modded Blacet rack too!
also look on ebay! I found a weird console type rack. :love:
now I got to buy a busboard.
stuff IS out there.

If I can find some supplier cheap (and good) enough I might be able to do a little production run, putting a few together. summer project though.
I think I'll mount it on a 19" pull out tray of some sort.
