Any advice would be greatly appreciated as my computer knowledge is limited
Would you like to tell us what resolution is your monitor?
I don't recommend that you get the H60 cooler. If you want it to cool well, it will be really LOUD! Water cooling still uses fans. You are better off with a quality air cooler.
That being said, you don't need a full tower case.
Besides that, everything else looks fine.
Erm I'm not sure I think it's 1920x1080 but I'm not sure Ive lost the manual and it doesnt say on it, the monitor is a lg 3d tv dm2350d, oh right what fan would u recommend? Is there anything else I could do add to it? Thanks. Rob
