Need help choosing a PSU and a cooler for my new PC build

[Roma]

I'm ok with having water in my system as the reviews I've read/watched say that its literately impossible for water to leak though one guy said it did. I'm guessing he did something wrong with it :P

I'm still not sure if I will overclock the CPU, I don't think I need to though, not for a while at least.

yup I won't buy a cheap PSU just to save money and risk everything els.

thankfully i still have until the end of next week to decide

thanks for the tips and links guys, very much appreciated :)
