Please advise re: build and timing

I am looking to have a custom computer build and will probably use Avadirect because they have all the components I want to use.

Here's the way I have it configured:

I will add a Sandisk Extreme II 480GB SSD as a boot drive and a Crucial 960GB SSD for data, along with a couple USB 3.0 or Thunderbolt drives for data and backup.

Application is mainly photography with some light video and maybe some light gaming, probably upgrading the graphics card at some point down the line. I am purposely choosing a motherboard that can do Thunderbolt and 802.11ac.

I *definitely* don't want to build it myself. I know it'll save me some money, could be fun, isn't that hard, would be educational, and shouldn't take long. But I don't want to do it.

Questions:

1) Any bad choices here (other than not wanting to build it myself)?

2) Should I wait for PCIe SSD? My new Macbook Air gets close to 800 MBps read and write speeds with the 512GB PCIe SSD, and my fastest SSD is just a bit over 500 MBps

I figure PCIe won't be mainstream in PCs until next year at the earliest, and I don't want to wait until then. ~540 MBps vs ~780 MBps isn't all that big a deal I guess.
