Should I upgrade my case?

[TPBlaster]

I currently have a Zalman z11 plus and im looking for reasons to justify upgrading to a define r5, c70, or a 750d(Other than they all look amazing)

Hi, i like the Corsair over the Zalman because there is more room for air flow, it has two front intake fans opposed to one on the Zalman, it has removable and re configurable HHD trays, 2 extra pci slots and a larger side window for show.

i'd just try and sell the zalman 11 and try and buy the corsair 450D. its a sweet case.

if you want a clean looking build, the nzxt h440 is great.

Unless you cannot fit something new in your current case, then I do not see a justifiable reason to migrate cases.
As you didn't mention temps, I'm guessing your current temps are fine?
If so, it would further decrease the need for a new case.

Your money would be better spent upgrading your hardware!
