My next move will be getting a Mac Mini as a dedicated music server. Right now I'm using a Macbook Pro, but I use it for everything. I've been doing some research about the Mini and there are lots of tweaks, optimizations and upgrades to do with it, but there is a clear consensus that upgrading the power supply brings about the Biggest improvement. There doesn't seem to be a lot of options for companies that do this upgrade. I know there is Core Audio, Mojo Audio and others....
Has anybody tried the power supply upgrade for the mini? Whose upgrade did you use and how did it sound?
