I'm pretty much only fond of PSUs and Cases and Fans, I always suggest a non modular powersupply over a modular one, first of all modular ones cost more and are less efficient.
To casing: Get a case that doesnt have a hundred airvents and predrilled holes, fans from the side or on the top will just suck in dust in abnormal amounts, I run two fans in the front and one in the bottom (one on my gpu and one on my cpu as well) all entrences are filtered which reduce dust by a lot.
Fans: Get some other fans then the ones that come in your case, case manufacturers always cheap out on them and they are utter garbage, you don't need the most expensive noctua fans just get decent pwm ones and you'll be fine.

Everything looks nice there besides that GPU, there is no point of buying that at this time. (It just doesn't make any sense over the new 7xx series that nvidia has.)

Buy like a GTX 760 or 770(this will do wonders)

I am going to buy a 120hz BENQ XL2411T (cost like around 250 euros for me, but I think you can get it for 250 dollars in the murica land :p, it should be a really good monitor)

As far as keyboards go, seems like a waste of money to me, note: I have never used a mechanical keyboard, that's just how I feel about it.

I would suggest the ASUS VG248QE as a 144hz monitor. There aren't many differences between that and a BenQ, for only $250 +/-.

Edit: It also often goes on sale on Amazon so you could snatch one for $240 or less if you're lucky.

Don't want to sound like a prick for any AMD fans out there but ATI cards will be a hastle in the long run. Their drivers blow. You'd be better off with Nvidia like raiku said.

Mechanical keyboards are not necessary but if you'd really like one, I'd go with Ducky. I prefer brown switches but that's just me. http://www.overclock.net/t/491752/mechanical-keyboard-guide Hopefully that guide will help.

For keyboard I very highly recommend the Hippopotamus Choc Mini or the Keycool 84. Both absolutely phenomenal TKL blue switch boards. Also nVidia is the way to go, ATI drivers are notoriously shit and their cards are noticeably weaker. Good for budget builds, not so good if you want a powerhouse

e: what the fuck autocorrect. Noppoo Choc Mini*

When I was building my computer recently I found r/buildapc and r/buildapcforme to be fantastic resources. You can also find great deals on hardware through pcpartpicker.com, which is run by a guy from r/buildapc who started doing it full-time.

Before you throw down a thousand dollars, I suggest you spend some time with those three resources so you end up getting the best computer for your specific needs, spending money where you know it'll do you the most good.

One of the reasons the Nvidia has their new line of 7xx series GPUs and AMD does yet is because AMD's previous 7xxxHD series are still very VERY good cards. AMD has really stepped up their game in recent years and improved a lot. Personally I feel all they have to do this year is lower the price of their cards and they would still be very competitive against Nvidia's new cards. To be honest Nvidia has had some serious driver issues also so it's not just an AMD problem.

For the build, a great budget GPU is the GTX 760 sitting at $250 range, if somehow you can find a AMD 7950 for the same price on sale I would personally go for the 7950 because it OCs easier and actually can out perform the new 760 card in some areas. There is absolutely no reason to get a GTX 660Ti or a 670 now because even if they are on sale and match the same price as the 760 I would go for the newer card.

For the SSD I would suggest maybe a Samsung 840/pro, or wait for the release of the 840 EVO which has been getting a lot of great reviews.

As for HDDs I would go for a WD Green for more storage, Reds are more for frequent read/writes in a more industrial setting. Blue for a bit of everything.Blacks are the best performance but realistically HDD doesn't really impact gaming performance at all. For personal use I would rather have the bigger storage from Green.

The Hyper 212 is one of the best selling coolers for a reason. when it goes on sale you could grab it for about $15 and personally any other coolers are a waste of money unless you get into the ~$100 range with NH-D14/SilverArrow/H100i/etc. stuff.

Keyboards are difficult to recommend. Believe or not there are some people who can't stand mechanical keyboards (I know right?). Try going into stores and try some out. I would go for a Filco Ninja Majestouch-2, but I don't think my CM Storm QuickFire is going to break anytime soon.

I have the ASUS VG248QE 144Hz monitor. The increase in quality from 60Hz to 144Hz is similar to going from 60fps constant to 350fps constant. I love every aspect of it and would suggest it as a less expensive alternative to a comparable benq.

Edit: dont forget the price of the OS

Why aren't you running lightboost, it's infinitely better :(

The difference between the VG248QE and XL2411T is pretty much just where they're cheaper to get. It's the same panel, so if you're in NA you can probably get the Asus for cheaper, and if you're in the EU the BenQ would be less expensive (from what I've heard). Getting the 4670K without a cooler is dumb, you might as well go with the 4670 for $20 off, since stock cooling is never very good for overclocking. The 212/evo is a great cooler for the price, and should get you a nice stable OC on the 4670k, if you're willing to pay the extra $30 for it. So basically $50 for OCing, if you're intending on doing so.
