This was my first build and i'm very happy with it. I use it mainly for gaming and browsing the web. I'm still learning a lot and ill give my thoughts about each different part of my computer.
CPU: I'm still learning about all of the CPU temps and as of right now, i havn't messed with overclocking or temps yet, simply because i am not completely sure how to or if it will mess anything up. I plan on getting the hyper 212 evo heat sink because the stock fan is too loud and i plan to overclock. Also putting the stock fan on was a bit scary because of the force required to attach it to the board. For the CPU itself, without messing with any technical details, it is awesome.
Motherboard: Originally i planned to get the Extreme3 rather than the Extreme4 but because my case has 2 USB 3.0 ports on the front and i needed a 20 pin header since i bought a cable to change the male usbs on the case into the header. My friend recommended the Ex3 because he said it would be all i need and the Ex4 has been everything i need.
Memory: has worked perfectly fine in dual mode and i would recommend it. Got it for a little more than $50 and i would recommend it. I do hate the force required to put the Ram in though because it feels like i have to push harder than i should have to.
Storage: Lots of storage for a good price, not much more to be said. I plan on possibly upgrading with an ssd in the future just for the op system but i am going to wait for a great deal.
Video Card: This thing is awesome. It came with Tomb Raider, Crysis 3, FC3 Blood Dragon, and Bioshock Infinite but i havn't gotten the code for bioshock yet. It handles all the games with ease while i havn't touched overclocking the thing. $254 was a bit more than i wanted to pay for the video card but i'm glad i went with this one. Another note- This thing is pretty big. It almost didn't fit in my case and i had to move my hard drive up a few notches to make sure the sata cables could bend.
Wi-Fi Adapter: I had a scare with this because i thought it didn't work. I bought it super cheap and expected it to be cheap but after getting windows to go, we couldn't get this card to work. We then found the CD inbetween the little things of cardboard in the packaging and then downloaded whatever was on that in an attempt to fix the issue. Our one mistake was setting the boot priority to the CD disk rather than the hard drive which contained the OS and we took about half an hr to solve the problem. After numerous restarts, we still couldn't get the card to work and were about to give up when we moved my computer upstairs to my room and it somehow worked. I still don't know what happened but it's working now so it's fine by me.
Case: I love the design of the case except the materials look a little bit cheap. However i got this case for 30 bucks so i'm happy with it for that price tag. Since i didn't buy a modular psu, my cables are jammed into the back which is just a little bit too thin. Cable management was a little tricky with the small amount of room but i don't think i did too bad for a first timer. I also knew about the issue of the usb 3.0 beforehand so i bought a adapter and different motherboard and it works fine now.
PSU: Quiet, good looking, and enough power. Everything i need for $30. I switched from the semi-modular version just to save a little bit of money. I'm glad i saved the $20
Optical Drive: Works fine and was cheap. All i really need.
Operating System: Windows 8 is either a love it or hate it. I prefer windows 7 more but i like some of the features of W8 so i downloaded a "mod" called classic start and i love it now. Also i could have got it for less but i forgot to order it because i was going to order it separately from BestBuy because i had a gift card. I forgot to order it in the mail so i went in the day i was building the computer and they didn't have any in stock. So me and a friend of mine went to tigerdirect and got it there. More expensive but there when i needed it.
Monitor: This thing was a steal for $130. 1080p, hdmi, built in speakers, everything i need... except an audio out for my headphones but that is no big deal because my computer has one.
Mouse: I bought a E-3lue cobra or something for $15 a few months ago on amazon and i love it. It looks sexy and matches my blue leds in my cases fans.
Keyboard: I need to buy one still. I'm using an old keyboard i found around my house and its keys stick and it just sucks. I either plan to get a cheap Logitech k120 for $15 or put some more cash down $40 for a Thermaltake Knucker. I'm not sure yet need help picking!
I need help overclocking and getting all of the settings right with my fans and temps and such any advice would be appreciated!
Edit: I recently picked up a cheap k120 keyboard because i had to barrow an old one from my parents, a refurbished corsair force 60gb ssd, and a hyper 212 evo.
Edit: Old mouse broke so I picked a Etekcity M555 up off amazon for $15. Works great for such a cheap price. Also added a new headset and Corsair case fans!
