help buying an I-Mac

[valtaherra]

I will soon be purchasing the 24 inch I-Mac. (applause)

Can any previous buyers give me any helpful hints, suggestions, or warnings before I make this purchase?

Any suggested upgrades from the standard package?

I plan on running up to 4 sites at the same time along with PA Hud, PT, Itunes, and 2+2. It is fully capable of this, correct?

Will my Western Digital external HD be fully compatible?

Thank you.
