As per thread, searched the serial number and it's come up with this

It has the school mark printed into the side as my sister brought it from them when they upgraded. Works as I had it on this morning trying to work out what's on it!! When it turns on 'mac os x' comes up it that means anything!

Has apple keyboard with it too.

£100 but open to offers.

I have it at my house in Bodmin but can take it to mothers when I have work.
