I've already got a 4000T with an MK2 060 in it (no SCSI on it). Let's say these have the Quikpak 060 in them - would it be better to sell the MK2 and keep the Quikpak or vice-versa? I'm thinking of piecing out my current 4000T and picking one of these up. I know the MK2 will at least pay for a good chunk of this 'new' one.
