I don't see any compatibility issues, but here are some suggestions.
Motherboard: MSI Z77A-GD55 ATX LGA1155 Z77 DDR3 3PCI-E16 4PCI-E1 SATA3 DVI HDMI VGA DX11 USB3.0 Motherboard ASRock Z77 EXTREME3 ATX LGA1155 DDR3 3PCI-E16 1PCI-E1 2PCI SATA3 DVI HDMI D-Sub USB3.0 Motherboard
Nothing wrong with the motherboard you've chosen, but do you really need Quad SLI/CFX? The MSI Z77A-GD55 is just as good and you'll save a bit more money; MSI is part of the big three so you can't go wrong. The Asrock Z77 Extreme3 looks like a pretty solid as well, Asrock might not be up there with Asus, Gigabyte, and Msi, but they're really coming into their own. The goal here is to shave off $$$ as much as possible for a higher-end video card without compromising on quality.
Ram: Patriot Viper 3 16GB 2X8GB PC3-12800 DDR3-1600 10-10-10-27 1.5V Memory Kit - Black Mamba
The Corsair you've chosen seems to be sold out. The Patriots above are on sale for an awesome price; they look nicer too.
Videocard: Galaxy GeForce GTX 660 Ti GC 1006MHZ 2GB 3.0GHZ GDDR5 SLI 2xDVI HDMI DP PCI-E DirectX 11 Video Card Gigabyte GeForce GTX 660 Ti OC 1032MHZ 2GB 6.0GHZ GDDR5 2xDVI HDMI DisplayPort PCI-E Video Card MSI Radeon HD 7870 Hawk 1100MHZ 2GB 4.8GHZ GDDR5 DVI HDMI 2XMINIDP PCI-E Video Card
The GTX 570 is an absolute steal for that price, but you're really missing out on performance from the newer cards like the 660ti or 7870. Pretty irritating cause just yesterday NCIX had an XFX 7870 Core ED for $189.99; they're all sold out now.
SSD: ADATA SX900 2.5" 128GB SSD SATA 3 SandForce 2281 550MB/SEC Write and 530MB/SEC Read Samsung 840 Series 120GB 2.5in SATA3 MDX Solid State Disk Flash Drive SSD
Although personally I'd go with the Samsung, there have been reports of problems during testing; the Adata SX900 is a great substitute. Nothing against Sandisk, but like I said in an another thread, they just don't have enough high profile SSDs for me to care about.
HDD: Seagate Barracuda 2TB 7200RPM SATA3 64MB Cache 3.5in Internal Hard Drive
Western Digital Black Caviars are excellent drives, but they're a bit noisy when they're running. I had two WD Black Caviars 640gb ran in RAID: 0 and the noise was pretty irritating at night. You get an extra TB with the Seagate Barracuda, and it should be a lot quieter (not to mention less expensive).
PSU: XFX 750W PRO750W XXX Edition Single Rail ATX 12V 62A 24PIN ATX Modular Power Supply 80PLUS Silver
The PSU you've chosen is solid, but unless you absolutely need a PSU from Corsair, the XFX 750W is just as good and quite a bit cheaper. Linus bought an XFX psu for his new rig, so rest assured that XFX is a quality brand. NCIX had the HX750 for $99.99, but like the 7870, it's sold out. Bond's suggestion for a 650W is a good idea, except there's not a lot of 650W power supplies on sale this time.
Cooling: Antec Kuhler H2O 620 Liquid CPU Cooling System LGA775/1155/1156/1366 AM2/AM3/AM3/FM1 + 2000RPM
Why? Well... why not?
Case: Corsair Carbide Series 300R Black Gaming Case ATX 3X5.25 4X3.5 Front USB Audio No PSU
The Corsair 300R IMO looks nicer than the Antec 300. All-black interior, LED Power button, dual rad support, cable management grommets, better airflow capability, and it's gonna be very hard to get it at $50 bucks again in the future.
Edit: found two more feature rich cases at a great price. Fractal Design Arc MIDI Tower Computer Case 2X5.25 8X3.5INT No PS Fan Controller & Front USB3 Fractal Design Core 3000 Black ATX Mid Tower Gaming Computer Case 2X5.25 6X3.5INT No PS Front USB Summary:
Provided that you went with the Samsung 840 SSD and MSI Z77A-GD55 motherboard, your total (tax included) comes to about $650.00. That leaves you with $450.00 left for a videocard...more than enough for a GTX 670 or even 7970...BAM!
