This list will help..
If I was you I'd nab a Silverstone Decathalon 850 Watt PSU. It supports PCI-E 2.0 with a 8 pin plug as well. This way when you do get a new board in the future you can use the same powersupply if you wish. Try to stay with Tier 2 and 1. If you can get a Tier 1 go for it. They have a few choices in the Decathalon series from Silverstone ranging from 650 to 750 to 850 watt versions. This way you can SLI in the future as well if needed.
I also see you're trying to collect all asus parts?...It may seem nifty but it's actually not the best idea. If you're getting a 8800 GTX get an EVGA model...Lifetime warranty as well as the EVGA Step up program. The step up program basically means you have a 3 month time frame to trade in your card for something better. You just have to pay the difference in price. If we do end up getting a new high end either it be a 9800 or a refresh of the 8800 (would probably be named 8900) then you can step up.
I haven't heard much about the silent knight cooler. But I would recommend nabbing a Thermalright ultima 90, or Thermalright Ultra 120 extreme. Thing is they don't come with fans...But when coupled with one (they have brackets to mount your own fan of choice) they are the best coolers by far. If you get the Thermalright Ultra 120 extreme...grab this fan with it..If you are worried about buying your own fan and don't like the idea..Then you can nab a Tuniq Tower heatsink...which has the fan already built in..it's just 1-4 c lower then the Thermalright Ultra...

You can get this fan cheaper from other places though...Everything else seems good...BUT...I wouldn't nab those corsair sticks...

These are also good modules that run D9 micron chips. If you plan to OC you want D9 micron. Corsair is beginning to switch out most their modules with IC chips which aren't very good for OC'ing. Whatever choice you make..Try to grab the model number of the modules you're interested in and give a google serach to find out if they are D9 micron chips.
Not sure why you are nabbing a dual core though. But if you don't plan to overclock it's fine. But if you do OC grab a quadcore instead..The Q6600. It makes a lot more sense..Especially since the future of computing heading for multicore..May as well adopt the trend now and have this reg perform better later down the road. Software will take a turn for multithreading with time. Crysis is already on that route...If you do any video/editing/3d modeling work also then you will benefit with the extra cores.
Besides that your rig seems fine. Although I personally find the striker extreme to be way too expensive and not necessarily worth it in my case...as long as you want it then go for it...good looking rig so far.
