it would be great to purchase directly from Netgear power supplies for routers like they are doing at Dell,
Yours friends could try a plastic cover that you fine at most office supply stores it has spit on one side so you place the cables or wires in side of the cover made to hide wires in an office buts works to protect them as well. But your right there should place to order the correct power supply if you need it. Have do really payed attention to the size of the connectors that Netgear is using or the ratings of the pwersupply that Netgear either I still say if the power supply design allowed it to live in the router a simple lamp cord style power cable would be the best answer one cord for any router they make. The only increase in cost per router would be the needed shielding around the power supply to keep its rf noise away from the other electronics.
