See @Vow3ll above. I generally don't advocate putting devices in an Eurorack cab if they've already got a cab and power of their own. Plus, you're taking up a TON of space doing this...with three Moogs in there, you're using nearly half of the cabs' panel space for just those three. Save that space for devices that have NO cab and NO power of their own. Then, as @sacguy71 notes, the "helper" modules you need will have space in the build, which will then benefit both the Eurorack build AND the Moogs once they're out of there.
And that's without even going into the cost-per-hp thing.
