I bought one of the 1.5TB external Seagate drives that was on sale 9 ($139 on-line from Frys, $149 from best buy).
I have 300 gb at the moment of FLAC on a htpc w/m-Audio REVO card in the closet behind my setup where I have a cable throught wall for connection. this provide silent operation in the listening room.
i can display my library on the HT screen using Meedio or I use remote desktop and often FooBar to run the jukebox from my laptop.
