If you're wondering if you should buy the low end iMac and replace the drive, or are a bit nervous about doing it yourself and figure the extra money for the larger drive is worth it, this How-To on Replacing Your iMac's Hard Drive might help you make a decision.
InstinctTech DogFighter CudaDemo is a great look at the latest in GPU and video card technology, with the ability to have 4000+ planes (plus hit detection and flocking behaviors) on screen at the same time. Lies, damn lies and tech demos and all that, still pretty impressive though!
Fellow geeks, I think there's no shame at admitting that when you read about SGI's 'Personal Supercomputer' that Handles 80 Cores, 1TB of RAMM you got short of breath and started to sweat just a bit more than is normal for the effort of reading a webpage.
