@Iggie FT02 and TJ11 are just the ones standing out. The TJ11 isn't really worth it over the FT02 if you don't plan to go watercooling (I won't go water with your ambient temps) since it's much expensiver but it looks aesthetics wise better. They breathe air from the bottom and push hot air through the top out, see here:

The cases like from Corsair or Antec are just brainless blowing air everywhere and will come with cheap loud fans obviously with poor static pressure since you want to aim to have the air blowing towards your parts and nothing else. The FT02 comes with 3 quality 180mm fans and a cheap 120mm you can replace. There are also ventilation holes for the GPU('s) you can see it from the top view of the case.
Just to illustrate everything:
Cable management might be hard but shouldn't be impossible at all and you still have the option to buy a fully modular psu in the future.
