I don't know about the Apple stores, but I know that the service centers and specialists can not get this kit as a "part", and Apple would not reimburse us for doing the install. I'm glad they're not saying we'll do it for free, though I'm sure I will be doing a lot of these for my customers as a service to them.

The things I've noticed different about the MD G4s and the FW800 ones for cooling are:
Different main fan with collar that almost touches the heat sink. (sp?)
Lower wattage PSU with different, quieter fans.
High efficiency heat sink (more surface area).
More holes in the back, a regular pattern, including in the PCI covers.
Different air intake design in the lower front.

Sorry, but I couldn't help but comment on the installation by service centers statement.

it's not that I'm too upset that I'll have to pay $20 for replacements (I have a Dual 1Gz MDD), but rather that I can't simply go to a store to get one. Instead, we're forced to order and pay the $20 for it- and if we don't want to instal it ourselves, then bring it to an Apple store and pay them to do it for us.
