[linux-audio-user] New Machine

Hi guys! (and gals). I am looking into building a new machine, and I want to do some home-studio recording with it. I was hoping that some of you could lend some of your expert advice. It sounds like SCSI is pretty-much a must in these situations, true? What I was wondering about in particular is if anyone has tried anything like this: Setting up a machine with an IDE hard drive to hold the system files (say an ata 133 7200 rpm...) and a scsi disk for the dumping ground of the audio programs such as ecasound, audacity or Ardour. I think I would put the swap partition on the scsi drive as well. Obviously I am trying to save a little money here, and I am trying to minimize latency. (I think that somewhere around the $2K mark is my limit.) I am accustomed to using multitrack analog units, but digital/computer recording is still extremely new to me. Any thoughts on this? I would also love to hear any suggestions regarding what disks, motherboards, cases and heatsinks people recommend and have had luck with. Thanks! Chris
