i've been doing my research, and i've got one question. what are the advantages of the opus over the ITPS + pw70 setup? i don't need the power of the opus, i'll only be powering an EPIA board with 7200 rpm hd and a 4 line text lcd display. or do i? all i've been able to come up with is that the opus is more power efficent, and that it will survive the crank. is that it? any input is helpful. thanks a lot.
