Update 2 (8/12/15): Added a Sound Blaster ZX as a means to troubleshoot an audio issue I wasn't satisfied with (long story) and decided to keep it for it's top notch sound quality. Everything has way more boom! Great set up overall.
Also, I added my Logitech G700s mouse and my Astro A40's to my parts list as well just cause.
Update: I added an additional MSI GTX 970 4GB GPU to give it a little umpf. I've added one picture for now and it's a phone pic. Pro pics coming soon.
Original: Overall, this being my first build, it took me longer to install drivers than the actual build.
Everything went smoothly. Build took about 1 hour for test build outside of the R5, then 2 hours to put in and tuck away cables in the R5's BEAUTIFUL casing. ASRock's install disc was full of bloatware but the essentials were there.
Ordered the GTX 970 BEFORE it was announced that it wasn't a pure 4GB card. Buyers beware, it IS 4GB but 512 is used for dump memory maintenance. Runs everything great without a problem though so for the price, it's worth it. And gorgeous.
The i7 4790k is a beast. Also comes with some BS in the form of Rapid Start which, if you can avoid it, do NOT install it. It's a hassle to get off and if you're running an SSD like myself, it does nothing to boot faster.
I added a Logisys lighting strip inside for kicks. Comes with remote and 16 colors. It was like $13 and just adds a little something through the R5's window.
The performance is fantastic, the price was barely over my $1400 price point, and it looks more like an extension of my living room than a gaming PC that screams, "I PLAY GAMES AND MY CASE SAYS SO WITH ALL IT'S FUTURISTIC LOOKING GLORY." I'm not a flashy person so I can't recommend the R5 enough.
