So after a year delay and saving, I've decided to finally go and build myself a computer. I'm not an expert but do have a general idea of how it all works.
Can anyone look over my build to see if it's all compatible and suggest any alterations if necessary.
I was also unsure about wether or not fan cooling was enough or if liquid was needed. This seems to be an issue that might be easily overlooked but with a potentially huge negative impact.
However, i'm happy with its current pricing but if it's a bit overkill in areas and can be reduced, then i'm all ears!
Thanks for the help guys!
AF.

I'm not sure if this is the correct link to my pcpartpicker.com build - https://uk.pcpartpicker.com/list/Wd7dpb

Also, how do i activate the operating system? I've not considered installing an optical drive so how would i go about applying Windows 10? Will the HDD have a preset?
