Thanks for all the useful advice. My final build consisted of:
Silverstone GD05B USB 3.0
Silverstone Strider Plus 600W Modular Power Supply
Asus P8Z77-M Pro
Intel 3570K
Corsair Memory Vengeance Red Low Profile 8GB DDR3 1866 MHz
Scythe Big Shuriken 2 rev. B
XFX 7950 DD Edition
OCZ Vertex 4 128GB
Seagate 3TB
Xebec iTouchpad Diamond Wireless Keyboard
3* 120mm Noctua NF-P12
64GB Corsair Voyager USB 3.0
Windows 8 Pro 64bit
Overall I am super happy with the build; it looks good, fits in my TV unit (tightly) and is pretty cool and quiet given the case/location/relatively high-spec components.
In terms of noise, in everything I have tried so far bar heavy 3D gaming it is reasonably quiet, though the Noctua's are slightly louder than expected, audible at ~600rpm (dissapointing given the price!) The 7950 is very noisy under heavy gaming, but again, I can live with that given the set-up.
Performance is awesome, Windows 8 is up and (fully) running from a cool boot in well under 10 seconds. Overall performance is top notch across the board. Load times from the SSD and Mechanical drive (for what I have put on there so far) are non-existent, couldn't be happier.
Gaming wise, of the 3 free AMD games, I have only really experimented with Hitman absolution, but in that, everything absolutely maxed, I am getting north of 60fps, looks amazing and runs super-smooth, I get about the same 60fps in Unigine, again, everything absolutely maxed out. Everything is through my 46" LCD, so 1080p.
Having problems getting Far Cry 3 running so far. Will update as I get a chance to play a bit more.
A couple of issues, firstly the screws on the Big Shuriken sheared when I was installing it, meaning I am currently running the stock cooler (which is actually pretty quiet), in terms of temps, idling/general desktop stuff the motherboard is about 29-31 and the CPU 26-30. The GPU is high 50's when gaming, again these are only prelimenary tests.
Applied the Asus auto overclock and the CPU is running @4.2GHZ.
I didn't take any photos when building, but will attempt to put up some photos if anyone is interested.
