I didn't know they still made 1 GB DDR2 sticks anymore, most of what I've been putting in desktops are 4 GB DDR3. It's actually surprising that they boast about power consumption and then don't do DDR3. Also surprising is the hard drive at only 500 GB. Whilst I realise that there really aren't any modern apps and that memory is fine for the old software that's available, you are up in the champaign and caviar price range and it would look nicer in the specs to see a 3TB hard drive and at least 4 GB of ram, even if it isn't really used.
The Radeon graphics card introduced 3 years ago may be a little long in the tooth as well....
