This was my very first build, which was just me going on Newegg and choosing what APPEARED to be the best bang-for-buck. Only long after did I realize how much I had screwed up, and how much better the build could have been.
AMD FX-6300 3.5Ghz 6-Core: The first in the list of bad decisions. While the CPU itself is fantastic, and I purchased the Black Edition for future overclocking, an i3-6100 would have been the better choice, since it would have given me a solid upgrade path with equivalent gaming performance.
Cooler Master Hyper D92: Somehow I convinced myself this was better than the cheaper Hyper 212 Evo. The D92 was very loud and let the CPU gain quite a few more degrees than I was comfortable with. It heated up my room over time, and the noise made me replace the case with a Define S later on, though this did little to help.
MSI 760GMA-P34(FX): A decent board, the FX-6300 sat pleasantly in its socket. But the SATA ports are in a horrible position, as half of the 8 ports were BLOCKED by the graphics card. This meant my hard drive was forced into a SATA 2.0 port. While this didn't hinder gaming load times by any substantial degree, I still hated having my possible storage cut in half.
G.Skill Ripjaws X 16 GB: The 8 GB of my laptop filled up frighteningly quickly -- most likely due to bloatware -- but it was still enough to make me double up for the PC.
Kingston 60 GB SSD: I wish I got a bigger drive.
Western Digital 1 TB HDD: Hard Drive. 'Nuff said.
MSI Radeon R7 370 4G: This is one decision I don't really regret. It's a solid card with a great cooler, plenty of VRAM, more than capable of handling games. The only regret I DO have is that I could've gotten an R9 380 instead. Still good a nice little overclock on Afterburner though.
Cougar MX-200: It was cheap.
EVGA 600B: It was cheap.
Monitor was a TV screen, which is why it isn't in the build.
Gaming was the most demanding thing I use(d) it for.
Unfortunately, due to my poor PC knowledge at the time, she acquired some driver bugs that I'm pretty sure I caused myself. The result of this was that most of my games crashed at some point, making them unplayable. I'd start a battle on World of Warships, fire off a couple shots, then BAM -- BSoD. Thank the gods of PC hardware, the SSD saved my butt with its faster-than-HDD speeds. Between hitting the restart button and returning to the match, I wasn't gone more than 40 seconds.
Anyway, because of the bugs, I eventually stopped using the PC altogether. It sits on the floor behind me, unused. I've considered what to do with her as the months passed, whether to reinstall Windows and try again, tear out the CPU and get new parts, or to give her away and make a brand-new build.
