Coincidently I have just been wondering whether I could make up the
cases cheaper than buying them ready-made from EMIS. Conclusion - I
doubt it. Firstly with only about £20 difference between the G3 and
G6 cases, unless you need a small case, the G3 is not very economic.
Also, if you join the 'Doepfer Owners Club' that Andy Horrell of
EMIS 'runs', you get about 10% off all prices - if you get a thirst
for more modules (very likely to happen...!) you recoup the 'joining
fee' very quickly. So, the DOC price for a G6 is £175. You would need
1 PSU and 2 bus boards to put in it. These are £44 and £23 resp,
total £90. This doesn't include any panels yet, in particular the
back panel with the power receptacle and switch. Doepfer do actually
sell these as 'spares', at 35 euros, say £25. This leaves £60 for the
side, top and bottom panels, all the rails and threadstrips etc. Even
assuming you could find someone to sell them at half this £60 figure,
the hassle in a) trying to find a supplier, and b) having to screw it
all together (one would probably need to order all the screws
separately as well....), for my money, just isn't worth the other 30
quid!!

But don't let me put you off too much - it _is_ possible to put your
own cases together, and the Doepfer stuff is a 'standard' size (but
there are several 'standards'!), so if you want to build a custom
rack or just happen to come across something that will do, then go
for it.

Haven't got anything other than Doepfer stuff, so can't comment on
others, but don't forget that the A-108 filter is also a Moog ladder
type (which I do have, and sounds good!).

Regards,
Tim
