Oven? Or fridge?

So here I am on pcpartpicker and after watching a video by LinusTechTips, he did a review on the Phanteks Enthoo Primo well... In awe by the shear size of this monster I decided to put it on my part list. But, here is a question. Has anyone messed with one? Or currently have an Enthoo? Because just because the case is massive doesn't guarantee I'm going to get low temps. So I want to know, does it really get good temps inside? Or is it just a really aesthetically pleasing case that is going to roast all my internals?

First post ever so if I put this in the wrong sub-thread let me know!

The top is completely open and has room for up to four fans, so it'll be easy to cool anything in there. Count on all of the noise to leak out too by the way.

Hmm... Well at least the case will be a fridge... The only thing I have plans to do for the case is leave the stock fans in. But replace the fans on the H100i I'm getting. Yeah this enthoo sounds like a plan!

Thanks for the help/opinion!
