First time doing anything more complicated than installing new RAM, and it was an experience. Terrifying, Challenging, Nerve-wracking, but when it started up for the first time I was like YES! Wanted a system that I could game on without lag or having the settings on lowest, and had been considering building a computer for a while. Took me about a month of working on the build on and off before I settled on what I have now. Despite the fact that it can be overclocked, it may be a while before I actually try it. I just want to bask in my achievement for while. :D My budget was originally 750, but I kinda got too into it and spent more than I should have :/
CPU: Nothing but good reviews, and AMD is way cheaper than Intel, which was a key point. Got a cpu cooler on the advice of a friend of mine who builds pcs, he suggested water cooling but for my first build I just wanted to stick with fans.
MOBO: Compared ASRock, MSI, and Gigabyte once I found a good enough model, and basically I couldn't find any difference between the three other than asthetics and BIOS, maybe a few USB ports more or less, but not enough to really make a difference. (I could be wrong) So I went with the Newegg deal that combo'd with the CPU, and I am very happy with it.
RAM: Newegg had a combo deal with the GPU and RAM, so I got it cheap.
Storage: Love the SSD, PC starts up in about 8 secs, I had an idea of what to expect from reviews, but actually experiencing it was something else. And you can't go wrong with WD.
Video Card: Spent more time considering this than any other part of the PC, finally decided on the 7850, when I noticed that the 7870 from sapphire was combo'd with the RAM, so it was a fairly easy decision from that moment. And I love it. Compared the computers I have had before, its like going from a 90s TV and VCR to a HD flatscreen and Blu-ray lol. Runs everything I throw at it with no problems.
Case: Out of everything in this build, the case is probably the only thing I regret getting, and even then I'm still satisfied with it. Cable management was a pain, it's not wonderful now, but this is after I redid it. The case looks great, but the temperature display is kind of a gimic, I ended up not even worrying about connecting the sensors.
PSU: 500w semi-modular from Corsair. Nuff said.
Optical Drive: Went with the Blu-ray disc drive. One of those things that I probably shouldn't have gotten, but it is very nice nontheless.
Operating system: Heard good things about 8.1, and I had gotten used to 8 because of the laptop I had used for over a year, so I figured why not, since it was about the same price as Windows 7 and Windows 8. Haven't had any issues with it, and it does what i need so I'm happy with it.
Overall, I'm happy with it. Oddly enough, once I put it together I wanted to do it again. This may be addictive!
