CPU: Simply get a Ivy Bridge processor, but dont invest on higher clock speed. As you are building desktop, TDP is not a concern, so get the ones with 77W, this will give you more clock speed already for the same or lower price. I recomend the i5 3.2Ghz.
Mobo:Ivy Bridge socket. I like having the most I/O integrated features. So look for bluetooth, Firewire, and Thunderbolt. Any Ivy Brdige socket will certainlly have USB 3.0
Memory: 8GB is a great standart, go for 16GB just to brag, get any speed you like that is compatible.
HDD. As apparently you have cash to burn, dont get internal HDDS. Go for an entire SSD system, as this will give you more speed, no noise and no heat. Do get a external HDD for backup purpuses. If yo dont do this, its a bad build. External HDDs are small, portable and no noise, and cheap. They can also serve as media storage, while you go upgrading your system to SSD. I recomend the WD My Passport series, but a lot of external HDD are wonderfull.
SSDs: 250GB SSDs are very cheap nowadays and 480GB are affordable. I sugest building what you need for now, and upgrading when needed incrementally. SSDs are 2.5", so you can have 14x SSDs in a case, they fit! For the adapter, check:

NOW THIS IS IMPORTANT: the parts below are gonna be with you for an enormous amount of time. This is where you choose carefully
CASE: Get any case you feel its "so beautiful I almost cry" I like Bitfenix designs, and also Moneual.
PSU: As I belive you want a no noise system, I recomend the Cooler Master Silent Pro. This particular series has been of great buld quality.
FAN: For no noise Fans, Coolink makes some wonderfully silent fans. If you dont mind hearing low humming, the best company would be silenx. They have the best CFM ratio. Dont forget that you may plug 3pin headers from the fan to the motherboard, and control fan rotation with software under windows and thus reducing noise. You can use split headers for multiple fans on the same port.
Optical drive: Any Blu-ray drive recorder. This will probably be your last optical drive, as this thing may go away, just like floppy. Any brand is fine, but do try to get one blundled with some nice applications.
Speakers: I like Creative speakers, their desing are awesome. Logitech is a popular brand for the regular user.
Monitor: 22"is minimum and fine for most ocasions. If you can afford go 24". Samsung and Asus are currently popular brands, I prefer Samsung or LG. If you want to adventure in the 27", the Apple display is my only recomendation
Mouse: For everyday usage, get a touch mouse form Microsoft. For gaming, get a wheeled scrolled mouse from either microsoft or logitech.
Keyboard: I simply have to recomend this one:

Also, take a look at Logitech webistes for webacm, joystick and headset.
And to conclude....liquid cooling:
The best pump today is the Swiftech MCP35X. Its available as a unit, and also in integrated versions with the radiator/reservoir.
I cannot recomend you a videocard, as this is extremelly personal. If I were you, I would get a 2x $200 cards in SLI/Crossfire, and thats it. No need for 2x $500 cards today, as this same cards will be only $200 next year. You can get next year this setup for nly $400, and also selling the previews cars for some money.
Have fun dude.
