My new Digital Audio Workstation, mainly for playback of virtual instruments (mostly VSL orchestral stuff). Some of my music: http://onemanorchestra.com/
Might add a video card later, and replace the stock fan for something more silent (it's OK for now). The name for this machine was inspired by Transformers. The logo was created by a cutting plotter on grey vinyl.
This case is just wonderful! Looks great, easy to build in, very configurable (the drive bays), lots of space and very, very silent.
