SID + FM + SEQ Enlosure question

[selfservice]

Hi, I've decided to build a SID synth and a SEQ V3, to use with the MBFM just born this afternoon  ;D

I have got an old organ, and I've the tentation to put all this stuff into it or to put every instrument in a separate enclosure.

this is a photo of the organ:

what's your suggestions?

of course putting all in the old organ reduces cables, improves live capabilities, reduces cost, but reduces flexibility also: once connected no more chances to on the fly rearrange the setup... on the other side, many instruments = more power supplyes, more enclosures etc etc
