Pros: Fast Reliable (If you fix the PS) Quiet
Cons: Power Supply Issues

I purchased my iMac from American TV and Appliance! Wow, big mistake! I love my iMac but the quality of service from American was pathetic! The biggest flaw of these early G5 iMacs was the power supply, a capacitor would explode and cause the motherboard to fry. Luckily Apple issued a recall, but American did not know that so it took two months for them to fix it whereas it took two days for the Apple Store to fix my Uncles iMac without a warranty. Overall, I have yet to encounter any other major flaw in this Awesome mac.
