I built this machine to play games such as Arma 3, Dayz, BF3 & 4, Beam NG etc. and do your typical web browsing and media center tasks.
Originally my plan was to use a AMD FX6300 but as I did more and more research I liked the idea of the i5 more and more for its lower power consumption and better single thread performance, as well as having better upgrade options for the future. On a similar note I went with the Nvidia GTX960 as opposed to my original plan of a R9 280 because they trade blows in performance but the Nvidia card is much more power efficient (uses close to 100watts less than a R9 280)
Overall I really like how everything turned out, its a pretty quite PC even at full load and games look beautiful.
in addition to the parts list I also have two 2.5" drives hooked up that I had laying around, the 1TB drive is for all of my documents, games, programs, and other data and I have a 320GB 2.5" drive that I have windows installed on and the last 2.5" drive is out of my laptop that this computer is replacing, its in there for data transferring.
Plans for the nearish future are to get a better CPU cooler along with some more case fans. I'm thinking I'll go with a water cooler for the CPU since the case limits me to a cooler height of about 155mm. I might also use the EVGA step-up program to upgrade to a 4GB GTX960 card that I found out today will be coming out soon.
Loaded temperatures were taken after temps leveled off while running tests in EVGA OC scanner X (GPU load was at 100% and CPU load was at 98%). While playing arma 3 on ultra I haven't seen the GPU over 65 or the CPU over 45
