Again, thank you for any help given.

Anyone?

With some research, the pricing is not really much the same:S

Any build suggestions on a quality UK site (like the aria.co.uk)?

Also does anyone know how the build in the first post holds up?

Thanks I will consider the PSU that you suggested.
What about https://www.aria.co.uk/Products/Com [...] ctId=43594 ?

I've revised my build to support more ram, and a better gpu, but reduced my HDD, tell me what you think, better than the last?: https://www.aria.co.uk/WishList/8fzLrFWlR5fHJHkwQmCeaA,,

Do I need a CPU cooler?
