1080p, £1K-ish rig, silence

[elitehellokitty]

I've decided to go with a Non-OC'd, Non-SLI, no water cooler, 1080p aimmed rig.
I want the set up to be compact and silent as possible without blowing the bank.

Fractal Design Define R5 Midi Tower Case - Black Pearl *-£10ish reduced price*
MSI GTX 970 OC Aftermarket (0-30dba)
Asus Z97
i5 4690 3.5Ghz
Be Quiet! Dark Rock Advanced CPU Cooler (18.8dba)
SSD: Samsung 1TB 850 EVO SSD 2.5" SATA 6Gbps 32 Layer 3D V-NAND (silent vs HDD)
TeamGroup Vulcan RED 16GB (2x8GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit (TLRED316G1600HC9DC01)
Microsoft Windows 8.1 64-Bit DVD - OEM (WN7-00614)
SuperFlower Leadex Platinum 650W Fully Modular "80 Plus Platinum" Power Supply - Black (semi passive cooler so lower dba)

Approx Build: £1,224

------
Erm the prebuild ones come with 7.1 Audio, which part is that?
Do I need a 1TB SSD? Or save money on a 500GB one?
A few websites advise 650w for a OC graphics is that necessary?
What parts would you tweak?

Thanks

I've stepped the SSD to 500GB might get a HDD given whats said. I think there is possibly diminishing returns on this whole "silent thing" , the GPU will hit 30dba on full load reguardless

As for case...
Fractal Design Define S- is cheaper, same design, less HDD cages I'd never use, 2 less USB on the front *shrugs*.

In terms of going smaller there is the...
Fractal Design Define Mini MicroATX Tower

Bit dated looking intakes, though.

What about PCU fan?

External DVD/RW, barely use the thing and its easier to port over for next build.
