Breaking the SLA means that any contract between Apple and you is void, and therefore you have no right to make any copies of the software, which includes installation, backup, and copying into RAM to execute the software. You even lose the right to install it and use it on a Macintosh. Furthermore, MacOS X has copy protection, and you can't run it on a non-Macintosh computer without circumvention of the copy protection, committing a DMCA violation.
Now I personally don't care if you tell someone that Apple won't catch them, and even if they get caught Apple will very likely not sue them, but don't tell them that it is legal.
Courts are not impressed at all if you misquote the SLA. It says "installation on a single Apple-branded computer at a time". I'm not qualified to say who precise or vague this is, but your Dell, HP, or home-built computer will _not_ qualify as Apple-branded. And Apple's SLA has just stood up in court quite nicely, when Judge Alsup said "this is what Apple's license says, so that is what Psystar and its customers are bound to".
And you left out:
Now I don't know if it is your attention span that kept you from reading the complete sentence in the license, or if it is blatant dishonesty, but that is the second time you misquote Apple's license.
