Fully Loaded Apple PowerMac G5 with display and Medea RAID Drive.
I bought this around 7 years ago to work on uncompressed broadcast footage and it cost me over £7000 then. For anyone wanting maximum power to edit video of photography this is the perfect system. It's also loaded with Final Cut Pro 7, Adobe Photoshop and tons more. (I actually have two of these units so I may throw in a second one for free)
