COOLER MASTER HAF 912 vs Corsair Carbide Series 300R

they are both excellent cases.

Like the other poster stated both of them are great cases. The 300R is a little more up to date and has a few more goodies, but both of them have plenty of room to tuck away cables while using a few zip ties. If I had a choice it would be the 300R for the extra fans and front 3.0 USB ports along with the 2.5" SSD cage.

The Antec 300 two is better than either

but of those choices I'd take the HAF advanced

What makes it better...?

Was that a question directed at me?

The Original HAF is nice but does not have front USB 3 . The advanced version does , and its well made but I dont like the style

The Corsair 300r has a top thats completely mesh . This wont help cooling but it will increase component noise getting out

The Antec 300 two is cheaper than the corsair , potentially quieter and has better cable management

Yes.

they are both great cases but I would have to go with the HAF

here are some pictures to make your decision easier-

The thermals are interesting . It nukes the corsair 400

The most thing I'am afraid of is the cable management and the air flow which one is better at it?

The HAF912 doesn't have its cables plugged in!  

Get the 500R  

almost everything except gpu.

oh yeah OP is trying to find a case for $50~ and you are suggesting a $100+ case? sounds dumb!

Whoah there buddy, ya seem a bit mad o_O...    
The 300R has better cooling, and has room for an H100, ceiling of the case is specifically designed for it after all. Enough said there.

Good point . The OP didnt mention water cooling at all though , so the case is worthless overspend compared to the HAF or Antec 300 two

and motherboard and HDD and there is no optical drive that build is just not completed
