Speccing out a macmini

[doublehelix2]

Hi

I'm not really knowledgable about macs, but I have an iphone and I need a pc update so I'm thinking of getting a macmini.

I have some questions though:

How well does the performance of the mini compare to say the imac? Does anyone have both or would be able to offer any sort of real world usage comparison? I don't really want to drop an extra £300 if there isn't much real world benefit.

Is it possible to put an ssd in the mini?

Is the mini powerful enough to handle say 7 usb devices all plugged in?

What are the limits with regard to gaming? (I'm not sure about the gpu in it)

Thanks for any help.

Ok cool, so the imac. Is it possible to swap the hdd in it for an ssd and not void the warranty? I really want the increase and ssd is the top of my list.
