To be honest with you, we got nervous just watching this video. However, should you want to change the processor in the new Mac Pro or just get an idea of what's in the tube, this is a great 12 minute watch.
Keep that metal tube on your desktop with this rather ingenious clamp and cable from Maclocks. The New Mac Pro Lock solves that security slot problem.
Apple have announced the New Mac Pro will be available from tomorrow, Thursday 19th of December. Full press release published. (Although it says it can be ordered, maybe not purchased.)
