well i don't see how you can build your own mac
and...Cubase for Linux?/Open source/win?
That would be one reason why I didn't say "Build your own, regardless of OS preference".
Ardour 2 can be built with VST support, so in principle you could get a GNU/Linux recording setup if your devices were supported. Unfortunately, bazillions of common devices *aren't* supported, so you're stuck with interfaces made by companies that don't consider themselves too cool to write another driver... but if your devices work, it could theoretically be done. (I'd say more, but I haven't recorded much lately and don't exactly know the current state of things myself.)
TheWinterSnow... a few years back nobody had dual-core support, but people bought dual-core anyway for the few programs that had support and the comfort in having a slightly more 'futureproof' system. Some applications today can use quad, and even those that don't can benefit from not having other processes trying to compete for time. If the price difference is acceptable, go for it... we'll be seeing support for these things soon (plenty of programs, anywhere from scientific computing to other multimedia editing, already have support for 4+ cores) and for the slight difference in price there's hardly any reason to stunt the system that much.
