240GB will run out pretty fast, I would recommend adding an hdd for mass storage. Also, get a better case with more air flow.
Here's my take on your build and it's only about $50-60 more dollars and gives you much better cooling and storage.
Otherwise that looks like a pretty solid build. (note I reduced your ssd to a 120gig to keep the price close) https://pcpartpicker.com/list/rhs2hq
Lol perfect I literally ordered everything except the case and data storage so I can correct those two now haha what a coincidence
That's perfect, you're gonna have an awesome computer!
I'd have to do my own research but is it possible to achieve the 144Hz with a locked Coffee Lake CPU?
this cpu and gpu could hit 144hz on low-medium settings in most games
