Any ways to improve on this workstation build?

Hi guys,

I'm considering building a PC to use at home mainly for work for me and my girlfriend. I'll only be using spreadsheets and relatively basic software but she will be using photoshop/AutoCAD/Sketchup/Indesign etc. Not too sure what's required for those computers but she said the PC's at work handle multiple programs/projects easily and the specs for those are:

i7-3770S
32GB DDR3
GTX 660 2GB

I want something with better performance than that PC, ideally under £700($1000) and using the Silverstone FT03 mini case.

There is the temptation to go all out on something like this:

Intel Xeon E5-1650 V3 6 Core 3.5Ghz
2 x 16GB (2x8GB) Corsair DDR4 Vengeance LPX
ASRock X99E-ITX/AC
512GB Samsung SM951 M.2
EVGA 2GB EVGA GTX 960 SC ITX
600W Silverstone Strider SST-SX600-G SFX
Silverstone FT03S-Mini
Noctua NH-L9x65 CPU Cooler
Noctua NF-A9 PWM Fan
140mm Noctua NF-A14 IndustrialPPC 2000RPM

That comes to £1700 total, I'm hoping that 140mm/2000RPM fan in the bottom of the case and that full size 92mm fan attached to the cooler would be enough cooling as that CPU is 140W and the GPU is 120W.

BUT, does anyone know a cheaper way of cramming 32GB RAM in that case?

 
The budget is open to be honest, I'll just go for whatever provides the best performance for the price while having better performance than that i7-3770 build.

The benchmark is that £1700 build, I'd like to see if we could find something that is better value for money in the £700 range though while still being better than the i7-3770 build and ideally using that case.

I hope that makes sense,
 
For anyone that may have been following this, the sensible solution is probably to make a small compromise in terms of size and noise and just go for:

Intel Xeon E3-1231 V3 3.4Ghz Quad Core
32GB (4x8GB) Corsair DDR3 Vengeance Low Profile
Asus B85M-G
Gigabyte GTX 960 ITX
256GB Samsung SM951, M.2 SSD
PCI-e x4 to M.2 PCI-e adapter
450W Seasonic SSR-450RT 80PLUS Gold
Coolermaster HYPER T4 120mm

That comes to around £800 and I imagine there isn't a huge performance loss between this machine and the £1700 one.
