Re: Build time
The build is well done and I would not suggest getting a cheap 680i over the P6N plat. The 650i Platinum is a very beautiful board with heatpipes and everything not to mention that the 650i chipset is an excellent chipset that has the same performance capabilities in SLi even as the 680i except without the bugs and FSB holes.
That monitor will most likely work but cheap monitors are cheap monitors so you can never be too sure.
I feel you are spending a little too much on a case...not that the NZXT isn't one of my favorite full sized cases next to the Gigabyte Aurora but i just dont like spending 150 bucks on a case. If you can find a Thermalright 120, or 120 extreme then go for one as they cost almost the same as the tuniq with better performance.
