Specs-wise, you've got the option of an Intel Core i7, Core 2 Quad, or an AMD Phenom II X4. You can pack it with a slightly ridiculous 12GB of RAM, and upto 3TB of hard disk space. There's ten (ten!) USB connectors, 2 e-sata ports, 3 firewire ports (who owns that many firewire devices?) and HDMI output, along with a multi-card reader.
