Just a heads up that you have to be careful with the partitioning on the early iMacs. Due to a ROM limitation, they'll only recognise a System Folder that is physically within the first 6GB (IIRC, it could be 8GB or some value around that) of the hard disk. Hence why the disk is usually partitioned whenever a larger disk is installed. It should be fine as long as you wipe the disk completely and then install a clean version of the OS, but if you ever reinstall on top of the current installation you may just get a flashing question mark at start up. You can either get around it by partitioning the disk in to a small boot partition and a larger data partition, or keep a copy of Norton Utilities on hand. Defraging the disk with Norton puts all the system files at the start of the disk, hence fixing the problem. I've been running a Rev. C iMac from a single 40GB partition for some time without any problems, though I had to defrag it when I first copied all the data from the original 6GB drive and upgraded to OS 9. I would guess that any OS updates might cause problems if they re-create the System file or the soft-ROM file – but I can't see any of them being released in the future [] ]'>
