Best budget Case

[otterfox]

Hi all!

Ive decided that I want to build a quiet rig because it's going to be in my bed room so I came here to find out one last part which I can't decide on: case.
It really comes down to a few cases,

Gigabyte TRITON 180
or the
CoolerMaster CENTURION C5 (with which I would replace the 80mm fan with a quieter one)
or
Gigabyte GZ-X1 (which uses a lighter gauge steel than the others and there for a lighter case)

Which would be quieter of my 76GB raptor + 500GB HDD, overclocked 3600+ under a coolermaster hyper tx HSF and a passivly cooled gigabyte 8600GT yet still keep it all cool?

edit: Here are some links so you can look at them(I can't buy them from newegg though)

I don't know about the other cases, but I wouldn't recommend the Centurion 5. It lets the hard drive noise right out at you, and if your Raptor is an older one, it's likely to have quite a lot of idle noise.

Which are the older ones? Im getting a http://c1com.co.nz/shop/step1.php?number=7878

I read the triton is ment to be a lot like the Centurion 5 just a different front and a 120mm fan at the front.

The gz-x1 uses 0.6mm steel,
he triton 180 uses 0.7mm steel and
the centurion 5 uses 0.8mm steel.

Does that make much of a difference?
