[rescue] Moving Sun servers?

[Vintage Coder]

Hi guys,

I have stumbled onto a cache of rack mount Sun servers and since I know virtually nothing I want to check if there are any issues moving and storing these machines. 

Do they have to be carried level or can I just grab one at a time and carry it without worrying? I don't have a rack and I am tight on space so I plan to stack them 3 or 4 high on each other until I come up with a better setup, will that be a problem? Anything else to look out for?

I'm sure I will have more questions when I get them over here!

Thank you.
