As usual my mind can never sit idle.

So i started thinking about NAS and getting a router that supports NAS , however it turns out that NAS units can be ridiculously slow, especially the USB types. Plus they are often limited to a single HDD.

And the actual Networked NAS devices are in a much higher price bracket.

OK, so i am thinkng if i should just build an NAS from an old PC. From there i spawned more ideas such as running an exchange mail server so that i can email my wife who sits across the table from me (yes, married 8 years) PC always gets more quality time with me.

Anyway, jokes aside.

I can always setup utorrent on it, or Shareaza if i want to download something.
Plus all the usual stuff like file sharing, etc etc.

What do you think value wise is the better option.

PS. I have an old IBM P3 667Mhz laptop if thats anygood?
