Skyrim doesn't require that much, so that would probably be able to run it.
That hard drive combo is a bit pricy. My build has a 3TB Seagate Barracuda which costed something like 110€ (About $150 converted, but it's cheaper in the US.)
Does the mobo have a wlan card integrated? The OPs build had a PCIe one, so I assume he needs it.
Yeah I guess I missed that part. Just throw in a cgeaoie $8 one and downgrade to 1TB if you can't go that high.
