Thought I'd covered that with my mention of DVD, Printer etc in my previous posting, but yes these things make a noise, however it's a different type of noise in that it's not the continuous same pitch wine of a fan or noisy HDD, and only occurs when you use the item. Normally I will install what I need from any optical medium to HDD then use a hack to bypass the requirement of having to have the CD in the drive if need be.
If someone ever makes a silent CD/DVD I'll be first in the queue same goes for printer scanner and all other noise making peripherals
