Alright broski, here's my suggestions:
1) For that budget (1100 euro is what? $1500), you can get i7.
2) Upgrade videocard to Radeon R9 285 or GeForce GTX 770 (770 is bit better)
Where you can spend less:
1) Case. You can easily cut 40 euros there with mid-tower (trust me, mid tower is large enough for 95% of builds) and contribute that saving to other more important parts. If you truly want full tower, i saw other cases for 55 euros. I would not spend 85 euros on a case with that budget though when you have bigger needs
2) Powersupply. Unless if you specifically want fully-modular, you can save 20 euros easily with a great semi-modular PSU.
3) Ram. You can save about 6 euros and still get same performance
Questions:
1) Do you need the extra Harddrive right now? If I were you, I would get the SD harddrive for sure but get the regular HD later when you need more space. HD prices continue to drop on basically a monthly basis - I suggest you get a second SDD when you need more space in future.
2) What is the max you're willing to spend?
My suggested parts:
http://uk.pcpartpicker.com/p/Xz7Byc -- I picked a random case - feel free to change that. If your budget is greater than that, I would first further upgrade the videocard as that is the single most important part for gaming. Get another harddrive in future when you need one.
