Additional Comments:
Well i think its self explanitory. I wanna build a super cheap server just for storage of all my files for my home network. I also want to be able to access my files anywhere i go.

I'm not really sure how to approach minimize the amount of money i put into this. I realize that i dont really need good hardware to pull this off, but i've been looking at craiglist used servers and i've seen single core (3.0ghz) blade servers going for $75. The only reason I've been looking at these is because some of them have raid cards, which i plan on using for raid 5 or 10 (havent decided yet).

I would also love to minimize power consumption because i'd like to run this server 24/7 or close to that.

Thanks for the help and suggestions guys.

bump?

Thanks, the only concern I have is will the eee be able to handle raid 5 with 4 or so drives? I might be able to get my hands on a cheap p4 with 1 gb of ram. Would something like that be sufficient to handle everything(2 computers accessing files at a time max)?
