I have a Power PC G5 Mac. I have a beautiful NEC 30" Hi-rez external monitor (photographer - side business). I have several e-sata external drives. I'm a K-12 teacher. I have a PC laptop through my school district. I want to upgrade to an Intel machine. I don't want to spend an arm and a leg for a new home/photo business computer. I want to use my 30" monitor and would prefer to keep my e-sata external enclosures (if possible). Mac Pros appear to fit my needs but they're so expensive. I don't really need another laptop. I've read the iMac has the biggest bang for the buck, but I don't need a monitor, though I could perhaps use it as a second monitor (correct?). The Mini doesn't satisfy my e-sata wishes and I don't know if it will support my monitor nor adequately support Photoshop and Aperture. So, which computer should I buy and why?
