Check out the auralic Aries. There is no internal disk because you don't want one in the unit. You get a 2TB disk now and what happens when you need more storage? How are you going to back it up? Another hard disk drive? Noise noise nois. Also, why would you ever need a 120GB buffer? You don't. You can load a song in memory in about a second. The Aries has an external power supply and a femto clock. Check the reviews from HI-FI+. The Aries also has the ability to connect external hard disks/ssd's. But you shouldn't have any hard disks in your audio room.
i setup a mac OS X server 100ft away from my audio room which has 10TB of usable disk space setup using raid 1. The Aries connects to this server by way of minimserver that runs on the OS X server. I use a GIg switched network so the latency is very low. I use xld to rip my songs and use Bliss to update the metadata. I use the OS X server for many other things besides running the minimserver.
I also have the auralic mini in my living that connects to the central minimserver.
