Mach2music for me. It's the combinTion of many factors such as how to use the bus, declutter the operating system, use Hard disk ans SSD in a sensible way and operate with Amarra and Puremusic. While one can probably get there on one's own, eventually, Mach2 music gets you there on the fast lane incl. offering firewire with cut power supply, etc. I think it's the most painless way to a decent server.
