PC Build Best Parts For $$$

Solution
As he stated it already owns the gpu.

New is case, apparently Board(?) and psu.

I gotta disagree with n0ns3ns3, the Seasonic Unit is quality but for that price the G2 is a no brainer.

The Fractal Design case is nice however the enthoo pro does come with better airflow and is one of the nicest cases in it's range. It depends on what's more important to you: best air flow (Phanteks) vs. low noise Level (Fractal Design)

Overall Gold choices on the New parts (We Can argue about the parts you already own though), build is only missing a Small SSD
I'd personally go with this computer case: http://pcpartpicker.com/product/nwVBD3/fractal-design-case-fdcadefr5bko
this PSU is a bit cheaper, http://pcpartpicker.com/product/TgW9TW/seasonic-power-supply-m12ii520bronze
but EVGA G2 comes with 7 years warranty for 10$.
I'd actually prefer the RM650x for the quite operation (fan is not spinning up to 266watt power draw and your system will run 99% of the time below that mark) and 10years warranty. today it's 100$ (same as RM750x) but usually they are going for 79$. Just need to watch the sales for a week or so.
 


Hey Tikizack, I believe that you can get a gtx 1060 gpu for around the same price of gtx 960 or less. 1060 is a newer and better performing card than 960. It also draws less power.

Edit: I am sorry; I misinterpreted his question; thought he was looking for best parts for a new build. Thank you Isokolon.

SRSLY ? better airflow? they have about the same shitty airflow (and same # of fan mounts) unless at least some HDD cages removed.
I actually prefer the Fractal for the cleaner look (thanks to the front door) and included fan speed controller - kinda better value.
But that's an opinion exactly like yours :)
As for the PSU - SS is the cheapest decent unit and I mentioned the G2 and RMx with their advantages so OP could make an educated choice 😉
