Re: [linux-audio-user] Scratch-built DAW - what's your favorite?

The current discussions re: RME cards and ProTools going Linux reminded me of a question that I wanted to refresh the list with. That is, building a DAW from scratch. Ok, I'm not talking about creating your own mobo, but to purchase a pre-made one, a processor, cards, yada..yada. I haven't seen this disussed recently, and was curious what others have done, and what others have used, to build-it-yourself. Can we start with mobo's? Any recommendations, horror stories, successes are most welcome. I recently built an AMD64 PC using a DFI K8M800 board, but it was for MythTV. I had absolutely no problems with the hardware. The problem was getting 64bit apps/drivers. I had to build most of it myself. It is getting _much_ better out there for the 64bit world, though. As I said, that was for MythTV. For audio, my latest is P4 machine is running FC2 -- with no problems lately. But, this is an older PC. Stories? recommendations?
