It's an old PIII mobo, I'm just about to start putting together a new computer so I thought I could start with a HD at first because I can use it in my old system for now since I'm out of memory. But when the new chipsets come out in the spring I'll buy the rest of the components. Actually if I only get 137 Gb out of this HD for now with my old mobo then it would still be fine as long as when I buy my new comp it'll be seen as 250Gb without having to repartition it.
