What is the most affordable/effective mac to buy to run FCPS2?

[Dennis Matuch]

I just purchased a 24 inch iMac
With the following configuration:
3.06GHZ INTEL CORE 2 DUO
4GB 800MHZ DDR2 SDRAM – 2x2GB
NVIDIA GEFORCE 8800 GS W/512MB
750GB SERIAL ATA DRIVE

I thank everyone for their advice. I am new to the forum and was very impressed by everyones quick and knowledgeable information.
I will let you all know how it works out in a week or so. Thanks again!
