I’m designing a NAS-style rack for MacBooks: five closed laptops, densely stacked in slide-in slots, fitting inside a standard server cabinet.
The cooling system would seal onto their existing exhaust vents and use a shared fan to create suction, pulling more air through the Macs’ own cooling systems, not just blowing air around them.
Slide a Mac in, lock it against the seals, and connect your cables.
If it can keep all five cool under sustained load, would anyone be interested? Most setups I’ve seen just stand them on their sides.
