And i expect that you will have no problemo's doing the surgery either johnno.
Well I have downloaded the repair manual and had a quick look at it. It does seem reasonably easy to work on, particularly as it comes in two halves. There is a docking station that has a spare battery, the DVD drive, floppy drive, USB port and game port. The rest is in the main body of the machine.

I think that the worst lappies I have worked on were the old Apple iMac3 and 4. It takes about 90 minutes to change a harddrive, and if you put the wrong screw in the wrong hole (there are about 20 of them) you will trash the motherboard.
