For the CPU of the new minis, I can choose between 2.0GHz (intel Core 2 Duo P7350) and 2.26GHz (P8400). I wonder if I can replace the CPU myself (now or later) e.g. by the P8700 which runs at 2.53 GHz. I heard that this is impossible. Even upgrading from 2.0GHz to 2.26GHz is said to be impossible. I was told that if I want the 2.26 GHz CPU, I have to decide so before I buy, as it is not possible to upgrade later. Is that true?
