I know I've posted a lot of these but I just want to be certain there is no problems in the build before I upgrade! Some parts I have and some parts I will be upgrading which I will make clear, I would like you to pick out any faults that I may have when upgrading my parts, e.g. good enough motherboard or if the case is big enough etc.

Cooler Master Vortex Plus 54.8 CFM Sleeve Bearing CPU Cooler

If you could take a look at the upgraded list and see what parts may need to be changed etc that would be appreciated and if needed, some good recommendations/alternatives.

I live in the UK and I'm not fussed on the price range as long as it's not too much!

Thank you
