faster and cheaper
You could save a bit of money on the case and get something that looks a little more professional and screams a little less 'check out my parts so you know what you are stealing'. I love my cooler master case I got for $40 (normally $60). It is the V3 Black Edition (sadly the V4 has an ugly front plate), but the inside is quite spacious and has a lot of good features. Or go for an entry level HAF, those are great cases and look much less childish.

I have a 27" Hanns-G monitor and love it for what I paid for it. Just be aware that they are not a quality company by any stretch of the imagination. There will be backlight bleed on the edges, and the color will be a little reddish on the left, and a little greenish on the right (mostly noticeable when on a solid white screen). On a smaller screen this will be less noticeable, and other monitors in that price range for a similar size/resolution will have similar issues, but it has still been a reliable screen for 4 years now, and was the only TN option in the larger size (mine was ~$400, while the others were ips screens for ~$1500 at the time, so I'll eat a little quality issue for having the size)
Dont bother with a fan controller. Just use molex connectors with resisters to kick the fan speed down to an acceptable noise level if your mobo has no built in fan controller option. If you feel that you must have one then get a cheaper one:

With the linked suggestions you would save $92, and if you do away with the fan controller entirely you save another $20
I dont know enough about AMD to comment on their motherboards and GPUs, but those seem decent enough. You may get more bang for your buck going with a similarly priced i3 matched with an H67 or P67 chipset motherboard, but you would have to check benchmarks for the specific titles you intend to play as the winners tend to go back and forth at that price level depending on the title. The nice thing about going with a nicer P67 board and a cheap i3 is that many will take the Ivy bridge processors next year, so you can buy a little i3 this year, and then upgrade to a killer ivy bridge i5 down the road without having to upgrade anything else (which cannot be said for an AM3 board). But I generally buy intel, and my only ventures into AMD builds have been for small power efficient sempron builds, and that was a long time ago.
Lastly, I just bought a 750W powersupply for my build with the intent of SLi for 2 gtx570s. 730W is way overkill for this build. You could likely get away with something in the 450-550W range and save your power bill a little. If you intend to xFire then go ahead an keep the 730W as you dont want to buy another power supply when you do, but otherwise I would go smaller. No qualms with the brand though, good choice, just too much power.
