Yeah, i'm not saying it's too much for the combo as a whole - just as a small project with recovered parts it's not really worth spending that much. If it was a brand new system, then it would have been a must buy.
As for the regular small case oiption, in my case it's not an option Maybe i could fit it behind the TV but the furniture i'm stuck with for now doesn't have much room for additional stuff (i am stuck to a 48/49" screen because otherwise it wouldn't fit).
EDIT: case arrived today - unfortunately i won't be able to bring it home until monday, but finally i'll have a reliable platform for all my streaming/playing needs. IIRC i can do Steam in-home streaming aswell, i just need to install the client right?
