Took your list as a baseline and modified it according to your needs.

Changes made and why i did them.
MoBo
Put in a MSI H170A PC Mate which is a good MoBo for i5-6500.
If you want to go cheaper on MoBo then you can switch it out for MSI H110M Pro-VD and save £40; while loosing 2 RAM slots. Oh, MoBo size also gets smaller, from ATX to mATX (micro ATX).

RAM
Put in 2x 4GB Kingston 2133 Mhz RAM to get you going.
You can always add more RAM since you have 4 RAM slots in total.
Storage
Swithced out Corsair SSD for Kingston SSD.
I prefer Kingston SSDs and RAMs due to their solid performance, great compatibility and low failure rate.
Also switched out Seagate HDD for WD Caviar Blue HDD for better performance to price ratio.
GPU
Switched out your GTX 1060 6GB for GTX 1060 3GB, while saving £68.
Even though 6GB GPU is about 7% faster than 3GB GPU, it's also about 15% more expensive. And thanks to this, 3GB GPU has better performance to price ratio.
You can switch back to your 6GB GPU if you like.

PSU
Didn't change it since EVGA SuperNOVA G2 is a Tier one PSU (the highest quality and most stable), while the Seasonic S12II series is Tier two PSU (slightly lower quality than Tier one).
