Stick with the E6600, good price / performance ratio.
Like someone else said, if you're not planning to go SLI, ditch the 680i motherboard. I know you are going with the combo, but you should be able to get a 965/975 with similar RAM for slightly less. If you are going to do some serious overclocking I would go with the 965, as they seem to tolerate the higher FSB's more.
As for the Raptor, it's not enough. They're great if you are going to have another drive for storage/apps, but all by itself, you'll be disappointed. Besides if I had one, I'd want two, so I could make a ripping fast RAID setup :twisted: .
If you are building this in the near term, I would consider either ditching Vista for now, or getting at least XP Home in a dual boot situation. Crysis / DX10 is a ways off, and besides nVidia's driver for Vista is not ready, and the leaked one BSODS (read -very unstable). If you are planning the build a month from now, maybe things will have smoothed out a little. I know it seems backwards to have a bleeding edge system, but then not use a bleeding edge OS. It's one thing to get Rev 1.0 / stepping A0 hardware, but never get Ver. 1.0 software including OS's. Good rule of thumb, wait for the first Service Pack. You want to use this system now, you don't want to be pulling your hair out for two months because nothing works properly.
As for the power supply, it should be sufficient for this build (just), but since you are building new (ie not carring any hardware over), give yourself a little more headroom to upgrade later. Sure this graphics card only uses X amount of current, but your next one may use 50% more. It really sucks when your upgrading your graphics card costing you $400 dollars, and have to buy a $150-$200 PSU. I've got nothing against OCZ, but there are more reputable PSU manufacturers.
As for the case, I have one (for the kids system). I liked it, but the system that's in it is slightly dated (P4C800-E Deluxe, 3.2GHz P4E, 7600GT AGP, blah blah) so I had no issues with the case. Later I was reading on a forum somewhere that this case had a design flaw making it impossible to mount PCI-E cards. Before anyone flames me, I didn't have this experience with the case myself, it's something I read somewhere. It seems to me that if this problem did exist, it probably has been fixed with a revision, but it's something to consider. Wouldn't want to start assembly and find out you couldn't mount that nice 8800GTS, that would suck.
As for monitor, not sure. I have a big a$$ 19" CRT, I like it, but LCD's have come a long way in nullifying some of there problems with games. I know LG has some nice models in the 19" widescreens, very high contrasts, good response times. I don't have much experience with LCD's when it comes to gaming. I have one on my wifes computer (Acer 19" widescreen) with a good published response time of 5mS, but she doesn't game. Maybe some of the guys here could give you some realistic advice (ie no 30" Dells too expensive for his budget), something that fits your budget. Also it doesn't hurt to hit the net and read some reviews, especially gamecentric sites. Since this machine is being built to game (otherwise why would you want an 8800GTS), besides the video card, the next most important component is the monitor. Put some research into this part of your purchase. Also monitors are a personal thing, if you've got a few computer shops where you live, go down to them and check out a few models. You probably won't buy from them, but at least you can see first hand what you'll be getting. It also doesn't hurt to buy locally on this item. This way if you get it home and it has stuck/dead pixels, you don't have to go through the hassle of shipping it back to wherever it is that you are getting this stuff. Most stores have a 14 day no questions asked return/exchange policy, so if you get it home and don't like it, take it back and get something else. Of course check this with the store you are considering buying from if you go this route.
Well have fun building this system. I assume this is your first build, so take it slow. Double check everything twice when putting it together before plugging it in. Most builds I have done boot on the first time, if it doesn't chances are you have forgotten to hook something up or something isn't seated quite right. Be sure that if you are removing / reseating anything to disconnect power and let the PSU discharge for 30 seconds before removing any hardware. You don't want to make a small problem into a big one. It's much nicer to have an RMA free build.
