Buying a new case

[nadavs2310]

Hello!
I wan't to buy a new case soon and I really don't know which one to buy, I have few that I like more than others but non of them are really perfect for me.
The first one is:
Carbide 400C Which I love the look of and I want so badly the easy opening of the side panel (it's one of my favorite case features)
the second one is:
Pure Base 600 (Be quiet) It looks alright (I don't love it look) and it has tempered glass but it does not include PSU Shroud and I don't have a modular PSU.
the last one is
Define C or Define S (what is the diffrence between them)
I don't really like their look but I heard they are great quality but also the side window doesn't look very good.

So what do you guys think, any other recommendation?

My specs are:
MSI R9 390X
I7 4790
16GB Ram
700W Max Pro Enermax PSU
Enermax Ostrog GT case
H97-HD3
and 2 noctua fans that I will probably keep that I bought after I bought the PC
NF F12 and I don't remeber the other one but it is also 120MM.

Be quiet Pure Base 600 is very quiet case, but it doesn't have good thermals. If you want silent case with decent cooling, I'd go with Nanoxia deep silence 3 or Fractal design R4/R5.

I don't care much about silent case, I care more about the look and the side window and the Airflow.
thank you for the quick awnser by the way.
