Renting a Mac OS X deticatied server.

Anyone know of a place I could rent one? Would it be a good idea to rent one? I plan to use this for hosting my website and a few other peoples websites. I currently have a PowerBook G3 Pismo i use as a testing server. I have a wireless network and truth is i'm not sure where in my house my powerbook is becuase I just use the X server remote things.
