I've just installed SQL Servewr 2005 on my main dev machine, and while I'm an admin (yes, I know it's bad but I [un]install lots of things so is just easier). However, since I had to reinstall my DC I haven't logged out, hence I don't have admin privs. Most of the installation passes, but some fail - Integration Services, VS IDE integration, SQL Books Online, and Workstation Components. Some I can understand, but Books Online? Why does that require admin rights to install? Weird.
