Decided to use this case for mine, should go well with the M2X.
Full Aluminum Amplifier Chassis Amp Enclosure Preamp Box 425*70*313mm | eBay

I will need to drill a few more holes for the other 2 input channels, I really like the idea that it has the shielded compartment for the PSU.

Haha, that's the same case I bought.

Is it a good fit?

I have a couple of questions.

First, how much heat sinking does the Mesmerize need?
I have a 2U Slimline chassis coming this week, and I was wondering if I could mount the B1 on one of the "pseudo" heat sinks. The B1 transformer is an Antek AS1215
The chassis will hold a total 3 transformers, an Allo Katana, and 3 Salas Ultra-BiB power supplies (4 power rails). I would not go so far as to say space is at a premium, but it is a bit tight.

Second, what are people doing for wiring to the output jacks? I am debating between microphone wire, coax, and just braiding the conductors and ground from something like 22ga solid core wire. I will be able to route them away from the transformers and power supplies, I am just not sure about how much I have to worry about EFI in this situation, so I would love to hear the experience and wisdom of others on this subject.

Thanks,
-Josh

2W dissipation per Mosfet i.e. 4W per side. 3mm alu chassis floor will do, not even needing the pseudo heatsink side. Unless you must mount it on the side if it fits. Or 3C/W heatsinks like FISCHER SK 81/ 50 SA, Aavid Thermalloy 0SY76/100/N etc.

I generally recommend coax and there are good quality small diameter microphone style types with two conductors and a shield from trusted manufacturers like Mogami etc.

Not sure if this is possible or not, I was thinking of adding a second pair of output connectors in parallel with the originals so I can connect to my WHAMMY, is there anything I need to put between the 2 outputs or can I just connect wires between the 2 pairs of RCA connectors.

Cheers

It's been successfully done many times before by other builders. Just put 100 Ohm resistors towards the secondary outputs hot.
