Upgrading current case or changing...?

I have a Cooler Master Cosmos S. It is a big giant. Overall I am quite please with the space, the cooling it provides (the airflow is phenomenal) and the aestetic. The cons are the cable management (it is actually quite good, but not exceptional, it coulb be better) and the noise (47dB at 12V). The good thing is at load, the difference of sound only coming from the graphic cards and a bit from the CPU fan.

My question is, should I invest money on a fan controller, fans and HDD bracket, about 60$...

Or should I just buy a new case altogether?

I am torned apart by the dilema of buying a new high end enclosure (waiting for the FT05) or just upgrade the one I actually have.

 
Yeah, but it is not for my current built. I need better performance and quieter system when idle. A fan controller is barely 30$ and drop around 9dB when I don't need LOAD situations.

Ahh, gotcha lol That'll be a bit more heat than a couple of 6850s lol

It's your call on the fan controller/new case issue. If you're happy with the airflow of it and the look of it, then I would say just stick with the case. You definitely won't find the same quality of a case for around $60, that's for sure, so you'd be spending a lot more to upgrade cases.
 
The other problematic here is... I can sold my whole system and buy a new case, or keep the case and and sell what I don't need.

Both way is fine with me and at the final, the new case fee will probably been cut by 100$ from the cash back.

It is not a lose lose situation, but I cannot pick either options so I am asking for advice >:/
