New system build (its been awhile!)

I'm looking to build a new computer (last one I built was ~5 years ago, which is now at the end of its upgrade life), and have been trying to catch up on current hardware. So I've cobbled together the following build from recommendations/guides/reviews, and would love to get some feedback on it, especially on any incompatibilities or space issues. But any feedback/advice is enormously appreciated!

APPROXIMATE PURCHASE DATE: Within the next week or two BUDGET RANGE: $1000-1200 Before / After: Rebates

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming, some coding, web surfing, etc.

PARTS NOT REQUIRED: LCD WS Monitor (with 1680x1050 res), keyboard, mouse, speakers

PREFERRED WEBSITE(S) FOR PARTS: newegg.com COUNTRY OF ORIGIN: USA

PARTS PREFERENCES: I definitely want an Intel CPU, and a modular PSU.

OVERCLOCKING: No SLI OR CROSSFIRE: No

MONITOR RESOLUTION: 1680x1050

ADDITIONAL COMMENTS: I would prefer a quieter computer, and that won't cause me any hassle down the road. Also, I will be throwing win7 64-bit in it.

The RAM, power supply you've picked is not good

5850 is overkill for 1680x1050, if you don't upgrade your monitor to at least 1920x1080

change the hard drive to a samsung spinpoint they are faster (suggested in my above build)

the case you've picked is not good at cooling, but it's quiet

you really need i7 860? since you only game..i5 750 will be fine
what kind of coding you do?

^The power supply you've picked is by a bad brand as opposed to corsair..
it isn't certified 80+...and is bad quality as opposed to corsair, that's why it's cheap.
you wouldn't want all your parts die because of a insufficient power supply

the RAM you've picked have high latencies CL9..it's cheap, but you could get better RAM with your budget. look at my suggested build that comes with a monitor above. my ram is 1333mhz with CL7.. yours is 1333mhz with CL9

again, solely on gaming i5 750 will crush anything that comes in the way making i7 860 not relevant in this case. i7 860 is like the equivalent of i7 920, it's for CPU intensive programs like video encoding, and other editing programs or designing programs

i believe my build fits all your needs at relatively a reasonable price.

you could wait for the christmas sale, black friday, cyber monday or whatever it's called in the US and save a few bucks

talk about no thanking me for helping, suggesting an entire build? hmm...interesting..
