Have a look at this:

Between F4 and F5

Look at the part when Timbarnes shows his set-up.

Russellc, Great link it answers many questions I and others probably been wondering about but had not been ready to ask. Still trying to get past the building stages. Forums are great, much better than a book. Books don't reply or offer multiple perspectives.

Thank you for digging this up. My boards (F4 and BA-3) came in the mail today. I already have the Mezmerize B-1 board. I may give the B-1/BA-3 a shot.

The plates by themselves are available in the spare parts section of the chassis part of the store.

What is the minimum heatsink required for building a stock F4 with-out running into problems ? Most of these amps are huge ! Could one use one of these enclosures ? See link > http://www.modushop.biz/ecommerce/cat079_l2.php?n=1

Probably something the size of the "Jack of all Chassis' 165mm x 300mm (6.5" x 11.8")

Of course you could run less bias, or use a fan. There are some very quiet fans available.

Would the above case work for a stock F5 ? The reason for my questions are I have a chance to pick one up half price. But I dont really need more stuff laying around till I find a use ! Its the one with 300 x 120 x 40 heatsinks. If not the F5 haw about a Aleph 3 or Zen Mods Babbel-fish with 2 output devices ? I have 90% of the needed parts for my F4, then this deal comes along (To much like Murphys law)
