$5AUD + $16.50AUD post for 1 > $21.50
Think that's still cheaper then scsi4me
20 would be same post cost, so $116.50aud = $5.82aud each
As you see I'm in Australia :D
It's not 70w though.. its potentially 240w (10w x 4drives x 6 connectors) - thats nearly 20A through one set of wires after the splitter..
As far as my searching goes, 18AWG wire can handle only 6A :o
