I know its been verified that the 2.0 is soldered. All the disassembled Mac Minis I've seen use the 2.0 CPU, but I still haven't seen anyone open up the CTO Mini yet. If anyone has any pics, I would really love the put this rumor to rest. Thanks in advance.
I would be willing to bet it is soldered as well. It doesn't make good manufacturing sense to socket one and solder the other.
