That looks like an ok case. The only problem I see is that it will not be deep enough if you go with the CoolerMaster Hyper 212EVO cooler or any other large CPU cooler, its just a few centimeters too narrow.
I have listed two of my favorite cases that do fit the 212 cooler or a variaty of other CPU coolers that are 120mm in size. Now I could not find a listing in Bosnia so I listed one in Germany, I don't know if that is close enough. It will give you the model number and specs at least and then you can look it up in local e-stores in Bosnia.
The Corsiar 300R is my absolute favorite Case, its large and has great airflow. Its also solid and has good clearance underneath so the power supply gets good air.

The NZXT Source 210 is also a great case, I use this a lot for clients. Its smaller then the 300R and its cheaper but it still has enough room inside to fit a large CPU cooler.

Let me know what you think.
EDIT: OF course you can stick with the silverstone case and get a Liquid cooler like the Corsair H100i. It will cool as well if not better then the 212 and it wont require anywhere near the headroom. the biggest downfall of the 212EVO is that its huge and takes up a lot of space in your case and can get in the way of your RAM chips if your chips have large heatsinks on them.
