Why no screen? The software interface for a hard drive system is a combo database/spreadsheet. It really inhibits the usefulness, particularlly when you store a large number of CDs, to not have at least a 12" monitor screen. One of the great benefits of hard disk systems is the ability to organize your music into customized playlists. It's just much easier to setup and access playlists when you're using a monitor. Also, if you get a dedicated hard disk player such as the Yamaha, be sure that you can readily expand its storage capacity. A 100 Gb system can store roughly 150-180 uncompressed CDs.
I'm not sure where Jtgale gets his info, but a Mac system with built in digital output (optical), software, monitor and external HD can be had for $1,800.
BTW, tremendous system. Have you considered the Linn or Goldmund HD systems?
