G5 fans...

[Riba]

Ah, as I suspected in my recent post, those fans might not be cheap to 
replace:

"The inside of the case is divided into four separate cooling 
compartments, and each of the machine's two chips is cooled 
independently.
Ive pulled out the twin fans for the chips, indicating the lack of a 
power cord. Because the fans have to be removed to insert more RAM into 
the motherboard -- an operation likely to be done only once or twice in 
the machine's lifetime -- they don't have a cord. Instead, they slide 
into a pair of power slots."

If it turns out you can only get a replacement from Apple, that could 
be a bit of a problem. :)

Ok, back to our Cubes now...
