Easiest way to transfer data from old HDD?

[frozentoast]

Like many, very recently I took the plunge: 27" iMac / Quad Core / i7 / 1TB HDD / 8GB RAM and I couldn't be happier!

What is the best solution for transferring data from an old hard drive (formally inside a PowerMac G5) to the brand new iMac?

My first attempt was with the 'Akasa Integral HDD External Enclosure' however this doesn't appear compatible with the file structure of Tiger, let alone Snow Leopard.

The PowerMac G5 tower itself has a failed power supply, so connecting from Mac to Mac isn't an option either.

Hopefully someone will be able to offer their words of wisdom, as at the moment I feel slightly lost.

What? External enclosures have nothing to do with file structure.

My mistake. For some reason when I connect everything together and turn the HDD on in the external enclosure, no icon appears in the Finder or Desktop suggesting it does not recognise this as a drive. Perhaps this has something to do with the HDD being Tiger and the iMac being Snow Leopard?
