Oh, you're good. When I said "shutdown" I just meant powering off. DOS isn't modern enough to really know anything about shutting down properly, you just kind of wait for the disk access lights to stop flashing and then hit power. Also, yeah, these are a phenomenal value. If you look at Passmark scores they're on par with an i7 920 which is quite a lot of processing power for $75-99 and <20W.
