quick question for the storage gurus... i have an old p3 600 in an abit bh6 with 768megs of ram that i was considering turning into my file server at home. this machine would be used for nothing more that a NAS device. i was thinking about throwing a raid card (PROMISE FASTTRAK S150 SX4-M for instance) and running a raid 5 array. would the pc's processor be a bottleneck if the computer's only application was a file server? thanks for any input.
