Well this is my first build and I tried to stay under $500. Better than my sh** laptop. You can see in the pictures the wires I taped up in the back, they are not visible in the front.
CPU: I wanted at least a quad core and this is what I got. I hope to look into over-clocking once I get an after market CPU cooler. For now the stock one is fine.
Motherboard: It's a great board for the price and I can connect stuff to it and it works. My only complaint is that it only had 3 fan header on it and so I had to wire 2 to molex.
RAM: It works great, its cheap, and isn't too unattractive.
Hard drive: its a working hard dive. yay. (it's louder than all my fans though.)
Graphics Card: This will probably be the first thing I upgrade. It works fine and came w/ a poster .-. It can handle games like Insurgency(recent update ruined performance, this is out dated) on all high and Besiege under normal circumstances(these are the only games I've tried so far). Its also Nvidia if you care about that.
Case: Looks great, made mostly out of metal, and has lots of dust filters (My room is very dusty). Its kinda cute being so small. The only thing bad here is the wire management. You can't really expect much for this size, but I did a total of 3 times rearranging stuff. #Neverforget
Power Supply: Works, 80+, but not much room to upgrade and its non-modular.
OS: downloaded free and command prompt "slmgr rearm" works.
Fans: Not too loud i can hear my hard drive and they look cool.
Headphones: Sound decent get kinda uncomfortable after time. (Pcpartspicker has them listed as $200 although they are only fifty at Best Buy.)
Wireless adapter: I forgot one and just went to Best Buy to get one.
Monitor: 720p :/ I really hope to upgrade this soon it works fine though.
All in all I can play games above 15fps and I have ascended from peasantry.
