Honestly, I have trouble justifying if I would want this simply because its Rosewill. I know there cases are excellent, but I don't trust their electrical hardware. The case is pretty much limited to an on/off switch and a 3rd party USB board. Not much to go wrong with. Now would I trust them with a power supply? No way. But a keyboard, that might be getting to the point of simplistic enough that I would trust rosewill to do it well.
Gold plated connectors is marketing nonsense at this point. Nothing is so dependant on voltage regularity it would need gold plating over other options in a connector. However, gold is softer and more prone to failure from repeated insertion which will happen alot for a connector.
