The cooling system is better on the Nine Hundred. But I agree, it doesn't suit an office environment.

If you're looking at an appropriate-looking case for an office environment with good cooling to match, this and this are what I'd recommend. I don't think it is worth paying the price premium for the P183\P193, considering the application.

Thanks, think I'm settled on the Antec Sonata then (I have the Sonata 3 case at home). I like the look of the Coolermaster though, so if I need to squeeze the costs down I may switch to that one.

Excellent. Let us know how it goes.

Ok, so my final build now looks like this:
