I've been doing a bit of a cost checkup on current 24inch iMac's (UK Apple store)
If you buy a 24inch 2.4ghz and then:
Add the 2.8ghz option for extra £160
Add the 500gb HD option for an extra £60
So now you have a built to order 2.8ghz version that matches the spec of the top model apart from RAM which is at 1gig rather than 2gb.
So all that comes to £1,368.99 which is £60.01 cheaper.
Now head over to http://crucial.com/uk/ and look at the RAM price - 4GB for just £72.84
So add that on to your £1,368.99 gives you at total of £1441.83
So for just an extra £12.83 you get 4gig of RAM (Apple's RAM is soooo expensive). You can then stick the 1gb stick you pull out and replace on ebay and probably get a £10 for it.
