hm, actually I'd suppose if you're seriously going to try it out and experiment with it, you'll be better of with the Pegasos. You know, the A1 Lite isn't there yet, so, using a Pegasos, you'll be able to get your feet wet and try it. And you have to admit, that you (At least) shouldn't have any drawbacks due to using a Pegasos. The only advantage of an A1 would be the possibility to use AmigaOS4, but you're not going to build a redundant server with AmigaOS anyway? And why would you need 2x500W. Are you really looking into doing this or is it more like just an nice idea?
