Apologies it took so long to type in a description, was too busy enjoying my new computer. :D
Anyhow, I was wanting a new computer to replace my 6 year old desktop, with its purpose being everyday computing and gaming. I had a current budget of around $600(which I got from tax refund), so I tried to get the best bang for my buck.
Essentially, my strategy was to get good base parts I wouldn't have to change out for a while(cpu and motherboard) and everything else just get "good enough for now" parts, with the plan being to upgrade those parts later. Then the parts I take out I will hobble together a decent family computer for my sister and nieces.
From what I've been lead to believe, the FX-6300 is a great mid-range processor, and it certainly seems that way so far. I won't be over-clocking it until I get a liquid cooling unit for it, but from what I hear it over-clocks to about 4.2 ghz with just the multiplier option.
Same with the motherboard, I heard it was pretty good as well. It doesn't come with onboard video, but that wasn't a problem for me as I was getting a graphics card. Certainly won't be running out of USB slots anytime soon, with the 2 front USB 3.0 provided by the case, 2 rear USB 3.0, and 6 USB 2.0. (Might be another 2 on back, they're labeled for the BIOS Flashback feature so I am not sure if they can be used as just regular USB ports.) Has a graphical BIOS mode, which is nice for setting up your system.
The graphics card I can't say very much about yet, as I haven't got the opportunity to really push it. Handles Elder Scrolls Online at max settings. Will update once I try a more demanding game.
The power supply looks nice and has performed well, although I plan on upgrading that to a higher wattage version in the future.
Update from original build: I have followed the suggestions from the comments and flipped the PSU upside down, so the intake pulls from vent on bottom of case. I also routed that power cable behind the board. Turns out the reason I hadn't done that to begin with was that it was kind of a tough reach, but once I flipped the PSU the cable reached the connector comfortably. I also added 2 more 120mm green led fans to the top of the case as exhaust and 1 200mm fan on the side as intake. It dropped my CPU idle temperature from 36c to 31c, and load temperature from 56c to 52c.
Thanks for the comments, all.
