I won't comment on the case, because I think aesthetics are up to you.
For the motherboard, I went with the ASUS Maximus IV Gene-Z because I've had many years of bad history with Asrock and their crappy motherboards.
The CPU is good. You didn't list a CPU cooler, so I assume you don't mind the annoying sound the Intel stock cooler makes and you'll never over clock it.
I've got Corsair XMS3 RAM - always performed well, although there's next to no difference between it and it's competitors from Kingston and G.Skill.
Twin Frozr II is currently the best value GTX560 Ti on the Market, and easily the most recommended. However AMD and nVidia are releasing their new graphics cards this month (or so I'm told) so if you can, wait to see how they perform before you buy the graphics card.
OCZ Vertex 3 are better than Corsair Force 3, but Crucial M4 are much better value (they recently released a firmware update that increased performance by up to 70%, giving it stiff competition with SandForce 2200 SSDs.
For the HDD... Stop. The only part where performance matters is the part of the drive with Windows on it. If you put Windows on the SSD, the speed of the HDD becomes irrelevant. You can save money by getting a Western Digital Caviar Green drive and see no performance difference. You could even get 2TB for nearly the same price. The only exception is if you use the Z68 SmartCache technology, but that is a pain to set up correctly (and if set up wrong, it does nothing).
For the Power Supply, I recommend Antec TruePower 650. It's relatively cheap, modular, and from a well recognised brand. Never accept PSUs from unknown brands - they're liable to explode.
