Clarification by S.Watanabe from Japan email@example.com:
>Isn't the Performa 275 the same thing as a Color Classic II?
Yes, it is about the hardware.
They are the same.
>Are there ANY differences between the stock Performa 275 and the stock Color
>Classics of yours besides the logic board and front name badge?
Yes, they are.
The hardwares without L/B and name plate are the same.
But I think there are some minor change on the hardware
(electrical parts or HDD capacity, etc.).
>Did the Performa 275 come with built-in stereo speakers (two speakers
>instead of one)?
P275 and CCII has only one built-in speaker.
It's same as CC.
