Sweet!

Which GTX 780 are you using?

I send the Akitio Box back to Macway

That's really a pity!

Nobody is using an additional cooler underneath the MBP?

@jcagara08: Giving the MBP a little more space underneath is sth. everyone should do under heavy load.

@goalque: Reducing the clock speed or the turbo is not exactly what I had in mind ^^

But of course, thats a solution as well.

How is your experience of a 15" i5 or i7 MBPr during gaming load in Windows? I would guess it get's pretty noisy. Are you running that MacBook on a "stand" for fresh air underneath it or maybe sth like a notebook cooler with a fan underneath the MBP?

The HDPlex needs a powerfull notebook powerbrick which are quite expensive. Something like 250-300W PSUs for Alienware notebooks.

Looking good. Regarding the PSU, a DC-ATX Converter might be interessting. With that you will "just" have another external PSU:

HDPLEX-250W-Hi-Fi-DC-ATX-Converter (16V-24V Wide Range Voltage Input)

&

Amazon.com: Dell AC Power Adapter Charger For Dell J938H Laptop Notebook Computers (Flextronics Flat Version): Computers & Accessories

That Converter should fit into the enclosure. Will give you a nice clean look.

What kind of fan is in the front? 80mm? Maybe you can use a pice of cardboard to guide all the air to the GPU.
