Well, I wouldn't even touch the Volcano 7, so you probably mean the Volcano 7+, and then the Volcano 9 is nothing special (except perhaps a low cost-alternative) and as for the Volcano 11 - like you said, best out of the bunch because its the newest, been developped for the faster/hotter CPUs, blah blah blah same sh!t as usual. What CPU is it to be used on anyways?
<b>Well, got DSL back - now I need to split my connection through my comp and switch, stupid new modem doesn't have built-in router... urgh. One good thing though - watercooling!!</b>
