Interesting point. Compressed air has always seemed
like hype to me. There's no problem vacuuming as long
as one doesn't touch the components. I've done it many
times with no problems.

My preferred method is to use both compressed air and the vacuum. With
my case ope, I run the vacuum and hold the hose up to the case. I use
the compressed air to blow out all the dust and it gets sucked into the
vacuum hose.
