My good friend Charlie ask me my opinion about some server/high-end computers, one of the options was the historically important Cray. Cray isn't producing their amazing systems that dominate the supercomputer field for years. Now they're producing high-performance desktop computers like the CX1-iWS.
Well, it's a nice computer with cool hardware but with Windows 7 as OS (maybe to reach some 3D modeling tools, because all the HPC software I know run on Linux/OSX).

This model in particular is being sold by Dell, I see the page to get more details and I found one of the reviews highly interesting:

Title: Helping our country's defense
Review:We have been using a few of these units for a while and they scream! I work for a defense contractor (Cyberdyne Systems) and part of the reason we were able to get the contract was by leveraging these units rather than a dedicated supercomputer. We've been developing new microprocessors for autonomous drones, and hopefully our use of these systems will eventually save lives! Cray has always been the Rolls Royce of computing, and our Skynet R&D team is thrilled to be using them.

hacking infographic

The IEEE Spectrum presents this interactive chart, really nice. I remember when people asked me how to hack a computer or email, I never know, but I found more interesting hacking genomes than machines.

Supercomputers future

An excellent article about this area "Next-Generation Supercomputers" [Peter Kogge 2011] . He pointed that the exaflops machines is far away, we need new technology to decrease the power consumption.

The PS3 comparison is cute too:
