Rebooting fanboy mode
Aha, it must be the mouse that makes it so expensive :P. Why did you include that? It costs like $20. Anyway, you can’t say that a Mac is expensive when you buy a 19" LCD display. Did you get a 19" LCD with your PC? If so, why did you bother buying a new one?
The high end Macs are expensive because they have expensive stuff in them like the latest graphics cards. If you buy a new PC with comparable spec, the G5 will be cheaper:
BTW, I just rendered a 10000x10000 image (Blender’s max) on my ibook with 384MB Ram using 4x4 parts. It was a simple image but the resolution wasn’t any problem.
