Looks good, I only have one suggestion regarding your monitor choice. Don't get me wrong, the U3011 is a fantastic display and it won't let you down. However, I would suggest taking a look at HP's
ZR30W.
The ZR30W features an S-IPS panel that offers excellent image quality that's comparable to Dell's U3011, however it's a bit cheaper and features much less input lag.
The main drawback to the ZR30W is that it does not feature an OSD. There's a few buttons on the side of the display that allow brightness and contrast adjustments, but that's about it. That said, HP's decision to omit an OSD actually has some positive side effects. Without an OSD, this display is much more responsive than other 30" displays. The ZR30W only lags 7ms behind a CRT, compared to the U3011's 25-30ms (that's two full frames of lag at 60hz!).
If you're going to be gaming a lot with this rig, the ZR30W will suit you better. If you absolutely must have an OSD, the U3011 will be required. Not having an OSD isn't that big of a deal being that you can just use the CCS (or NV control panel if you went with the green team) to adjust brightness, contrast, gamma, etc...
