Firstly Welcome to GeekstoGo
Secondly you should, if you have NOT already done so, go to each manufacturers site and have a look at the product there.
Here for instance is the Coolermaster forum and from there you can go easily to the site
http://forum.coolerm....com/search.phpHere is the motherboard ASRock
http://www.asrock.co...=SpecificationsOn there you can see the recommended RAM with which the board has been tested and the supported CPU`s.
and here is the one for the graphics.
http://www.hisdigital.com/gb/The case is Tool-less build and that means that basically all is clipped etc with no screws. Not to everyone liking. You need to ensure that normal fixings can still be used, as sometimes the clips break.
That all said in principle I see nothing glaringly wrong with your choices, but I would look closely at the idea of only 4Gb ram. That motherboard has ONLY TWO ram slots, so you cannot of course increase the ram without wasting one of the sticks. Personally I would go for 8Gb. Windows 7 64 bit requires a minimum of 2Gb itself.
HOWEVER the far far more important advice is this. This is your first build and you would not be the first person and certainly not the last to get it wrong and find out that you have made a very expensive error.
See this, please read it carefully and then my advice is re=read it. It is a guide written by our Staff members and is possibly one of the better guides available

http://www.geekstogo...d-wont-turn-on/My further advice is to obtain a computer, which is beyond its useful service life, but working. It does not really matter that it will not be the same as the one you are building. TAKE the computer completely to pieces. REBUILD IT. If it still boots you have it correct. If it does not - obviously on the face of it, you have something wrong.
For the sake of a small amount of cash, if you DO have to buy it, it could save you many times that amount.
Finally I wish you the best of luck.
We are here if you need any further help.
All the advice you need is in that article from our site.
I would draw your attention to the following points:
1. Take your time, there are no prizes for speed.
2. Choose a time when you can be assured that you will not be interrupted. Interruptions are t one of the prime causes of errors.
3. Choose your working area with due regard to anti-static.
4. Be especially careful when seating the motherboard, incorrect stand-offs or securing it incorrectly are frequently fatal errors when you power-up
5. Check your build at each stage.
6. Do NOT open any component anti-static wrappings until you are ready to use them.
Good luck
