These are my own questions - asked since the first mac mini was introduced:

- Why is the tooling so lame ?

- What do they, themselves, use internally ?

Stringing together mac minis (or a "Studio", whatever) with thunderbolt cables ... Christ.

I assume a company like Apple either has custom server boards with tons of unified memory on M series with all the i/o they could want (that are ugly and thus not productized) or just use standard expensive nvidia stuff like everyone else.
