This is my first PC build.
CPU - I went with the 4690k as it is the best i5 on the market. I'd have went with a 4790, but I couldn't afford it. CPU Cooler - I didn't want to stick with the stock cooler. Mobo - I went with a cheap option. Nothing special Memory - I went a little overboard with 16GB, but it was pretty cheap. Storage - I wish I could have went with an SSD, but I couldn't. I had a drive from an old PC I threw in for *****. Video Card - I haven't done much game testing yet, but it's pretty badass for what I need it for. Case - I love this case. For this cheap I think it's one of the best. It made my first build semi-easy. Power Supply - Fully Modular for optimal cable management. (which I need to get better at). OS - Pretty standard. Felt like getting the newest OS. Case Fans - If you ask why I got Blue LED fans with a case with Red LED front fan I will tell you I didn;t realize it until it was too late. It doesn't look bad though and they are way quieter than I expected.
Overall, I think the build is pretty good. My foresight was poor as my mobo doesn't support SLI, but I doubt I'll ever need a 2nd card anyway.
