This is my new build after being on 7-year-old hardware, which means that everything is new!
The build was done about two weeks ago, but I didn't want to post anything until I got the cables sorted out nicely. Cable management is a time sink, but worth it in the end.
I decided to go "all-in" on everything but the GPU, as I'm waiting for Vega to launch before I upgrade further. I didn't want to invest too much money for a GPU at this point, so when the RX 480 launched, I decided to purchase all the parts.
The CPU Cooler was a pain to install, and since it's so big it's covering up a lot of the motherboard, so it's difficult to adjust stuff where needed. It's a beauty, though! My other choice was the Phanteks PH-TC14PE, but I liked the design of the be quiet! one better.
Motherboard: It has what I need, and more. I'm not too fond of the BIOS, however.
Memory: 32 GB might be overkill, as I'm not doing any rendering etc. as of this day, but it wasn't much of a price difference, so I just rolled with it.
Storage: This one is interesting. I've always had more storage space when I had 1 TB HDD back in the day, but I was annoyed by its slow speed. That's why I opted for the best of the best consumer SSD. At a later point, I'll install a 1TB SSD or HDD, but I'm waiting for a sale.
Case: There was a lot of back-and-forth on this one. First I wanted the Phanteks Enthoo Luxe, then I got hyped about another case (which I don't remember). Just in time, however, the Enthoo Evolv ATX Glass edition released, and my god what a beauty. It had to be that one! I also opted for the Galaxy Silver color, because a pure black case seems a little boring to me.
Wireless Network Adapter: I have an Ethernet cable plugged into my machine, but I wanted the option to go wireless as well (and it has Bluetooth, which is useful in some scenarios). This makes it easier if I decide to go to a LAN party.
Monitor: Originally I was focused and ready for a 34" ultrawide monitor, but decided against it when I decided to go for the RX 480. The great thing about the MG279Q, however, is that it is IPS and can go in portrait mode, which fits perfect with an ultrawide when I decide to buy that in the coming years.
Update: June, 2017: It's close to a year since I bought and built the system, so here are my thoughts on it so far.
The monitor is amazing; There's no backlight bleed or dead pixels. The fans are relatively quiet at their lowest RPM (when the system is idle, i.e. no gaming and no rendering/compiling). I believe there are quieter systems out there, though.
My only gripe with the system so far is the motherboard. On the software aspect, there are so many applications, and most of them are very unstable and prone to crashing. At this point I'm only using an application called SIV (which controls the fan speeds), but in order to use this application, I had to download another application in order to launch it (really, Gigabyte?).
I would advise you to see how reliable the motherboard manufacturers' software and drivers are before you buy one. The software provided is an important factor to consider, and is not something to overlook.
It turns out that 512GB of storage wasn't quite enough since I started some video projects (and some games are 60GB+), so I bought a 3TB HDD for those cases.
All in all: I'm very happy with the build!
