While it's absolutely the complete, dial-to-11 antithesis of 
"supported", SL can be convinced run quite well on the new minis, at 
least the ones with the intel integrated graphics (the low end one 
and the server). I'm happily running SL server on a quad-core i7 (not 
for MCL, but to be a server) with great success.

I suspect it may well work on the mid-grade mini with the better 
video too, but that's a little more of a stretch since SL never 
supported the exact video chip that mode has, just others in the 
family. Not sure if anyone has proven what happens on that machine 
one way or another.

Getting there is nontrivial. You need both a SL-supported thunderbolt 
macbook pro and a copy of Lion. The basic strategy is to

- first, completely update the macbook pro with a copy of 10.6.8 that 
has all software updates *including* the separate thunderbolt s/w 
updates.
- 2nd, duplicate that OS/drive onto the mini over firewire using 
something like SuperDuper! or equivalent.
- 3rd, grab from Lion the data files that describe the cpu clock 
frequency profiles for these new machines and copy them back to the 
mini's SL system.

Lots of discussion about this here:
https://discussions.apple.com/thread/3209335?start=280&tstart=0
(though also a lot of confusion in that thread caused by people who 
didn't start with a fully updated thunderbolt system as mentioned in 
steps 1 and 2 above)

cheers,
john
