OT: Low-poer real-audio player

[Chuck Guzis]

I know this is off-topic, but I'm looking for suggestions and a 
solution may involve a "vintage" box.  If you feel that discussion of 
this on-list isn't appropriate, please email me privately.

Here's my situation.  I like to listen to web-based radio and I 
transmit an FM signal so that I can listen on any FM radio.  It works 
very well and I'm happy with that aspect.

However, the system doing this is an old built-like-a-tank 500MHz P3 
Compaq Deskpro box running RedHat somehing-or-the other (it's been so 
long since I've upgraded it that I don't remember) 24x7.  I'd like 
something that drinks less power.  Interface to the web is via 
100BaseT copper.  Station switching is accomplished via a simple 
shell script and initiated via telnet.

My current thought is that I could pick up something like an HP e-PC 
and equip it with a CF hard drive.  But a 1.7GHz CPU again seems like 
overkill for a very limited application.

Does anyone have any other low-power ideas?  Note that most of the 
streams I listen to are RA, not MP3.  

Thanks!
Chuck
