I think you also get a mouse and keyboard thrown in with the iMac, although that's only about another £70, you have however proved my point. IMacs are around £1450-1700 so you're slap bang in the middle really.
If you're trying to compare that to a Mac Pro then your spec is way off. For real comparison Dell start at £1k for a very low end Xeon machine, moving up to £3k for in upgraded versions. My workstation (at work) comes in at around £10k and that's an HP. The mac pros weren't that far off and when I looked last year were actually less expensive than their truly comparable HP bretherin in.
Edit: just to clarify a point, I certainly agree with you when it comes to upgrading models with apple however. Adding more ram or a bigger hard drive is where apple take the pee, although not so much on machines you can't upgrade yourself.

It wouldn't be right if it wasn't
