[linux-audio-user] A machine for live gigging?

I'm still very new to Linux Audio Workstations (I've been a Cakewalk/Sonar/SoundForge user for years), so please forgive me if the question seems very basic... I'd like to build a computer to take with me for live gigs that can replace sound module racks (do softsynth/sample playback, multi-timbral, polyphony, etc.). In other words can it replace an Alesis QSR, a Kurzweil K2000RS and a Korg TR? Can I do this and still have great sounds/synth/samples? So the question is can a Linux DAW do this? If yes, what are the specs for such a machine? CPU? RAM? Motherboard? Sound card (very important, eh)?
