My LMS is running on an iMac. External HD dedicated to music files attached with Firewire. I use dBpoweramp to rip CDs with this external CD / DVD burner attached with Firewire:
http://eshop.macsales.com/item/OWC/MR3F82SD24S/The iMac connected to router with Cat5 and a long Cat5 cable goes from the router to the PS Audio DS DAC with installed Bridge I in the music room. Use Squeezepad on an iPad as a controller. I ordered the Bridge II couple days ago, hope with it installed the network continues to work smoothly. Prior to getting the LMS plugin working, I was using the trial version of JRiver on the iMac and JRemote on the iPad. There are 3 days left on the JRiver trial. For my purposes currently I don't think I need JRiver, so might not spend the $50 to keep it.
My router is actually an Apple Time Capsule which is a combined router and backup device. It backs up everything on the iMac as well as the external music HD.
In the future I may get a Synology NAS and use MinimServer installed on it.
