I'd suggest hopping on pcpartpicker.com. Use the cpu cooler link, at almost the top right corner is a switch for details or list. Use the List, it'll pop up thumbnail pictures of the coolers, then you can shop much easier.
Corsair CXM 450 is a very good psu, better actually for Haswell or newer Intel than the Seasonic 520w as the Corsair uses DC to DC converters vrs the Seasonic group regulated design. However, either one of those psus is quite superior to the Evga 500b which is a pretty dismal budget psu.
As far as aios go, they are pretty much the same as an air cooler in their respective areas, a corsair h55/h60 gets the same performance as a hyper212/cryorig h7 or a corsair h100i v2 is akin to a Noctua NH-D14 or the H110 v2 is like a Noctua NH-D15. The only few differences are looks and fit, there's many cases that won't fit the 160mm tall coolers like the Noctuas or even the budget hyper212 or gammax 400. Most newer cases have at least 1x 120mm fan port where a small liquid cooler can be mounted, or even 2x 120/140mm fans can be swapped for a larger aio. So cooler choice is not always about budget, but more on personal tastes and realistic ability of the OC wanted vrs case cooler size availability.
If you can't afford bigger than a 120/128Gb ssd, that's fine, you'll just have to learn space saving techniques like installing games to hdd, but saved games are on ssd, dump prefetcher and superfetch, delete hibernation totally (don't just turn it off, it's still there), saving documents and download folders to hdd etc. You'll need to be frugal with space, you really do want to maintain at a minimum 10% of ssd space for windows usage, or better would be not to use up more than 90-95Gb max.
