Early Cheetahs were warm. By the time the 18G drives were coming out 
they got the heat issues solved. Damn fine drives in the greater than 
9G size.

I'd only ever worry about heat in an SS5 if I had an old pair of 'cudas 
and a CG14(is that right?) (Big dual slot framebuffer 24 bit type)

Geez dood, what do you want from more than 10 year old technology? 
Those boxen wiped the floor with PeeCee's of comparable vintage.

To answer your points the second generation SS5 was called Aurora II 
and yes it held a standard full size CD-ROM drive. As for the SS4 and 
SS5 yes you could transplant the board however the wimpy SS4 PSU likely 
would die if loaded with drives.

FWIW I ran an SS4 as my mail server for 4 years until the drive started 
to die so I switched to an Apple B&W 400MHz G3 running OS-X Sewer.
