Uber Thread of Hardware Questions.

I see one problem:

You've selected an H67 motherboard. That doesn't allow changing the multiplier on a k-suffix Sandy Bridge. (Basically, no overclocking.) If you wish to overclock, you'll need a P67 or Z68 motherboard.

A 500W power supply is the minimum recommended for the Radeon 6870. The Corsair one you specify may be OK, but you might want a bit more margin.

I don't own one, but the Cooler Master Hyper 212+ heatsink/fan is supposed to be among the best in its price range:

The Arctic Silver is a traditional favorite, but their Matrix product:

Arctic Silver Incorporated - Céramique 2

is all-dielectric. I think that it may not require as long a break-in period as the Artic Silver. I imagine that the thermal compound that comes with the heatsink is more than adequate, if you wish to save a few quid.

Will the 6870 fit in your case? (A part number would have been better than the low-res picture that you linked to.) The card is 26.2 cm long, which is fairly long.

You could consider a 6850 for the graphics card, such as:

XFX RADEON HD 6850 - Graphics adapter - Radeon HD 6850 - PCI Express 2.1 x16 - 1 GB GDDR5 - DVI, HDMI, DisplayPort: Amazon.co.uk: Computers & Accessories

You'll give up some performance, but it ought to be in the same class.

Buy the corsair h70. It is the best cooler on the market. The joy of water cooling without the headacks.

Noctua NH-D14 (air) is supposed to outperform the H70, as long as we're speaking of expensive cooling solutions. (The Noctua is absolutely humongous, of course.)

With the Corsair H70 I can overclock a AMD Phenom 2 B55 to 4.5 GHz with a very high vcore (1.60 volts) with all cores unlocked. The multiplyer is at 22.0. Idle temp is 37C and the max under extended full load is 59C. It has been running at this since the end of april and no issues.

Installing the cooler takes sometime and takes two people regardless what Corsair says. Took 3 tries the first time I used that cooler for a build I built for someone else.
