[LAU] "hi-fi component" PC cases or devices?

My home stereo is a pretty old-fashioned thing, and mostly I like it that way -- I have a record player that's a bit older than me, a CD player and amp about a decade old, and a couple of speakers. Occasionally I plug in a portable mp3 player. But I wouldn't mind adding some sort of "proper" box that can play audio files from hard disc. I suppose I want something that looks and operates much like a hi-fi component but that is just a PC on the inside. It must have its own storage, and not just expect to stream from another computer; must have a display on the front, and not just expect to be connected to a screen; should be mains-powered and quiet; CD-style transport buttons and some sort of selector dial on the front would be nice, rather than requiring a remote; wireless networking would be nice too; CD drive for ripping handy but inessential. Questions: 0. This must exist already as a consumer product, right? Where can I buy one? 1. Can anyone point me to a small PC case that could be used to build one? 2. What would you use to play audio files (gaplessly) using a dedicated LCD display as the user interface, on Linux? 3. Any thoughts on soundcard hardware for a device like this? The Brennan JB7 player (http://www.brennan.co.uk/) is not far off the sort of thing I'd like, but it has no networking (copying from USB drives only). This case: http://www.origenae.co.kr/en/htpc_m10.htm looks like a smart place to start, but no controls except a hugely overspecified remote -- obviously for home theatre rather than just audio -- and expensive for something that isn't really ideal. Any ideas? Chris
