These are no doubt custom fabricated racks. If you know what you need you can have anything custom fabbed. You won't be seeing any ads for them in the back pages of Mac World.... Are they still around ?
At any rate MacStadium has been around for several years and if they are currently thriving and expanding (here in the USA!) they have to be doing something right. Have a look at the pics of their Mac Mini racks and Data Center.... They're awesome. They know what their doing....
Hence the questions I posed above. Not saying it cannot be done, but seems a bit dubious given that it's for an unreleased product with minimal known specs. Unless they had some sort of special access to the pre-production version, but that's doubtful seeing as though they didn't even have the right specs listed on their site. Fabrication on this seems a bit premature without having a few units on hand to see if it actually makes sense in the first place.
And I'm sure you can agree coming up with a racking solution for a Mac mini inherently seems a bit easier than a tube not designed for it in the first place. They certainly wouldn't be the first successful company to introduce vaporware to the public. Not saying that's the case. But it's certainly not out of the realm of possibility.
Excellent points by Pete, I'll add of course one of the missed pretenses in the good doctor's reply: Popularity and/or the number of readers an article or rag receives is not a reflection of accuracy or probability. To prove this all one needs to do is visit one the opinion/discussion blogs about the movie series "The Matrix". All fascinating conjecture... and, of curse, about as realistic as that MacPro rack they showed - or a server comprised of 512 interconnected iPhones. Will someone eventually try and hook up 6 or 8 MacPro6,1's ? Probably. But trying to connect "270 [MacPro6,1 Desktop Grade] machines running as "servers in 12 square feet" and selling/advertising that as a "datacenter floor space" solution is ludicrous and improbable even with the most flamboyant imaginations. That would be about as probable and expeditious as attempting to build datacenter clusters out of thousands of MacMini units... Oh wait, they already claim that as well:

From the very same site.
Preposterous!
