Help with my Gaming PC Build. please help me

I personally have been using the Rosewill Challenger in a mid tower ATX gaming rig and it works for me just fine. The case is $49.99 USD and I would go with it over the Rosewill galaxy just because it has the two extra side mounts for fans if you need them.

The motherboard looks good

The processor is fine, but for about the same price you could get an AMD FX 8350 which has 8 cores instead of 4 and clock speed of 4GHz which can be overclocked up to 4.2 GHz and personally I would go with the AMD FX 8350, or you could get the 8320 if you can not spend what might be a extra couple pounds or dollars.

If you want 8 Gigs of RAM go for this: http://www.newegg.com/Product/Product.aspx?Item=N82E16820313355&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID= 2 sticks of 4 gig ram will out perform one stick of 8 gig ram.

For the HDD, I would look at something like this if you want to save money: http://www.amazon.com/dp/B0013DU7R4/?tag=pcpapi-20 Western Digital hard drives are great, but I have been using hitachi and seagate hard drives and have not had a problem yet, and they are cheaper for the most part.

I do not see any issue with the PSU, it is a decent brand and it should suit your needs fine and then some

for the graphics card, the R9 270x looks like a better option than a HD 7870, but the GTX 760 will outperform that. A R9 280x will outperform a GTX 760 and the 290x will hands down, but the 290x is getting near GTX titan territory.

I am not sure where you can get a legal copy of windows 7 anymore because microsoft tries to force windows 8 onto anyone they can, so you might have to get creative with that, but I prefer it to windows 8.

I do not know what you need your optical drive to be able to do, but anything should do as long as it lasts the half hour to an hour it takes to install windows, this one will do that and then plenty more.

The adapter will be fine if you get a large antenna for it and place said antenna in a good spot, but I would exlpore any options to have a direct wired connection that are possible first, especially if your gaming.

SSD's are nice, make sure you unplug your HDD when installing windows to make sure windows goes on the SSD and not the HDD though. I assume your getting the SSD to put windows on to have it boot faster.

Those speakers should be fine, but I am not an expert here by any means since I never got speakers on my gaming rig, I just use a headset.

The monitor is really at your discretion. However, keep prices and size in mind. for the price of a 32 inch I have two 22 inches.

The case fans are fine, depending on the case. The challenger case I mentioned above comes with a top 140mm, rear, and front 120mm fan with the front having LED's on it, there are two mounting points on the side 120 or 140mm fans as well, so make of that what you will. Case fans mainly depend on the case your going to use.

As a final note, I can not tell you how much I recommend you NEVER pay anyone to build your computer and NEVER BUY A PRE BUILT PC! In my mind and in the mind of what I think are a lot of gamers, you lose respect for someone that buys a pre built instead of building their own. Building a computer is a lot cheaper than having one built for you, my PC would cost around $500 USD more to have it bought from one of those "build your own computer" websites. I highly suggest you take 15 minutes and look up some tutorials or something, it is seriously easy. If your able to put the square peg in the square hole and use a screwdriver, you can build a computer. It is by no means hard, and if you need help I can get on skype or teamspeak or whatever you want and walk you through it step by step, I know a lot of people here are really nice and they would be more than willing to walk you through it step by step on these forums if you provide pictures, as someone did that for me on my first system, and I had a bunch of people helping too. People here are friendly and encouraging, and if you need any help putting the PC together im sure someone here can help. It honestly took me an hour with no instructions to put my first computer together, the parts are made to only fit one way. You may want tor read your motherboard manual when your adding the parts to that to make sure everything is in the correct spot, and use some zipties or something to keep wires away from fans, but it really is not hard, and it is a good experience to have and good knowledge, plus you get the satisfaction of knowing you built that computer.

Edit: Hope this helps

+1, the GTX 770 is a strong card.

the only thing I would change is liquid cooling. I do not see a use in it. High performance air coolers are cheaper and yield equal results.

The build I posted is perfect for you - just use that.

I would personally go with the FX 8350. It is better than the intel i5 4430 and it will run everything faster. The build you said you would use a couple posts up looks good, minus the liquid cooling. It is not bad, but I never use it because it is not needed, it costs more, and theres the chance of having it leak inside your PC.
