1300$ Gaming Desktop

Only thing I would I would try doing is knocking down the price with combo deals...
Other then that, the case is excellent! Reading all the reviews and looking at all the pictures, something told me right then and there that your going to get the right cooling solution.

Power supply is perfect, even if your going to SLI those GTX 460's(witch I highly reccomend doing since they scale up to 90-100% with current drivers).

Can't find a single problem I have with this rig... except maybe the cpu cooler.
It is a good cooler, but since this is my opinion I'm gonna say I'd go with the XIGMATEK Balder or the XIGMATEK Dark Night.

I currently own the Balder and its running on my AMD AM3 Phenom 925 3.0 ghz. Yeah, i know it's low speeds, but then again, even when It was overclocked at higher speeds like 3.8 4.0 my CPU was still ideling at a 33 C. With a load up to 43 C. (like during crysis or Heaven benchmark).

But hey, thats my opinion. I'm a XIGMATEK fanboy.. what can I say.

Anyways, your rig looks awesome!

You cant SLI nvidia cards on an AMD motherboard. Thats the problem you missed.

I have a Balder and a Hyper 212. The balder runs a few degrees cooler and looks a helluva lot nicer. Then again its $15 more so you have to decide if the looks are worth the money.

Corsair changed suppliers. The new 650TX is now made by CMT, not Seasonic like it used to. For me, the jury is still out on the current builds quality.

Seasonic has a 650W for cheaper so its easy for me to recommend getting it until the new Corsair 650 gets a longer track record.

The lower wattage Corsair TX line's stuff was originally made by Channel Wells, not Seasonic.

I'd go with a G Skill Eco kit $95

Option for SLI AMD mobo. Just be aware AMD does not support 3rd party chipsets.

You can get the XFX 650 W PSU. It's made by seasonic and is a lot cheaper after MIR.

Deja Vu all over again ... just had similar question:

i7-950 based system

Goal here was to provide for a system capable of a 4.0 - 4.2 GHz Overclock w/ little effort and provide enough oomph for adding a 2nd card in SLI at a later date.

$220 Antec 1200 w/ Antec CP-850 Top notch case and the PSU is incredible. Suitable for twin GFX cards and heavy OC's.

Personally, I'd go with the CAS 6 and spend the extra $40

Options if ya can't spend the extra $63

A factory OC'd EVGA GTX 460 1 MB will save ya $70

A Svythe 2100 CPU Cooler will save ya $60

Dropping to an Antec 900 / HAF 922 would appear to save you money but combining it with an SLI /X-fire capable PSU suitable for OC'ing puts you above the cost of the better case / PSU combo already in the build.

Dropping to the i7-930 would save you $20

CAS 8 / 9 memory just isn't worth the minute savings.

Dropping to 500GB or smaller again just isn't worth the savings.

You could drop down to an 1156 based system but that would put you in the $1100 range.
