I studied your setup some time back and may go that route in the future. Also, good to know about the Rosewill/D-Link Adapter interchangeability. What I was wanting to do for my current(no pun) requirement was to buy some of the slightly more robust/powerful power adapters with barrel plugs to replace what seems to be failed OEM supplied ones. I have read the thread and have noted the recommended ones but I have not seen/read any posts detailing specific experience with my contemplated plan with my specific hubs. Perhaps that information is in here but I missed it?
I now have the parts to make molex to barrel plug cables for when I have time to solder them up to switch to an 80+ rated supply with better efficiency.
edit: added need for plug adapter with the 4 amp power supply.
