I remember buying Musicmatch Jukebox at Staples back in the stone age...was better for burning CDs than being a jukebox. Had a guy from SC on a Usenet group for antique radios (a wind sailor and a bit of a mild scoundrel as well) who swore by his Archos.
I think there are probably software solutions that take advantage of already existing browsers such as Windows Media Player, Apple and are a bit more fleshed out than some of the media codec add-in players I've seen like VLC/Videolan and K-Lite.
I have an old micro-ATX Compaq case that I have pretty much gutted with tin snips to find room for a up to a 500W PS but all I have to mount inside is an ASUS MB with a 1500 MHz Pentium III. Let me see if I can find the pictures here as the USB floppy is placed somewhere at the moment.
That's gonna be a while it looks like. It has an arched full cover that I painted deep blue, the chassis a dark teal/green. The front panel is an apple green that ended up sort or translucent or antiqued looking (probably not the right type or a rust-preventer) with the top door left the original white. It has these 'legs' built in to the front and ended up reminding me of a 'ninja turtle'.
Well, chalk one up for artisitic merits.
