While you can certainly use WaveCenter/PCI with any computer that has an open PCI slot, multitrack digital audio is an application that requires a lot of CPU horsepower and disk space. We generally recommend going with at least a Pentium-II or similar CPU, and a fast disk subsystem with a 7200 RPM UDMA or SCSI hard disk. Slower CPU's and disks will still work -- but you won't be able to have as many simultaneous tracks.
