That's an expense rack. If the average MBP cost $1500, that's a total of $144,000 in the one rack. They must have some serious reasons to create something like this.

For a full rack that's not a ridiculous price. Oracle will gladly sell you racks that cost in excess of a million.

As will Cisco, or Dell, or HP.

I wonder why all of the display backlights are on? I understand having the laptops open to stop them going to sleep without an external display, but I'd've thought you could turn the backlight all the way to "off".

You can even disable sleep with closed lid[1], but addmiteddly that might intefere with ventilation, since there are vents in front of the hinge.

Only just realised from this that MacBook Pro's no longer have an Ethernet port! When did that happen?

You need to buy an expensive thunderbolt adapter. I can understand removing it from the ultra portable super-thin models but not from the top end professional model.

This is pretty neat, but I wonder how much more dense this configuration could be made if one took away the display, keyboard, battery, and chassis of the laptops and just had the motherboard, which (presumably) is fully integrated with a DIMM connector.

A $30 adapter for a $2000+ machine isn't what I would call expensive. It does make the machines a lot thinner though and normally, you don't need wired Ethernet any more.

I easily reach 60+ MB/s now over WiFi, so for the times where I really need the additional power I don't care about having the additional dongle with me.

There was similar post with ARM Chromebooks. A few years ago it was impossible to find stable ARMs which could sustain decent load without crashing. Company had to buy bunch of Chromebooks, strip batteries and put them into rack.

Yeah, I was disappointed by that, too. It's not about the cost, I don't care about the extra $40 or so, but now there is one more "dongle/cable" I need to worry about.

Why are you keeping the lids partially open and drawing excessive power for the displays + backlight, instead of just using InsomniaX [1] ? [1] - http://www.macupdate.com/app/mac/22211/insomniax

"They are actually being held open 7mm by a custom 3D printed wedge. This opening allows for the screen to be used for testing as well as ample air circulation. You can’t see the temperature sensors tucked into each notebook’s keyboard area."

Air circulation makes sense. There is a vent in between the screen pivot and the base, and also the gaps in the keys allow for some heat to escape.

Agreed that the screens should be turned off, though. Could just turn the brightness down to 0.
