Computer..realistic looking..:)

HI there...
I was wondering if someone might have an idea on how to make apicture of a computer..look realistic..and be able to use it..I don't know if anyone here has played many point and click games..but there are some that have really cool realistic computers. Even if they are done in paint programs...Just wondering how you would do it..I have an idea..But I'm not very good with stradegy..like knowing how to start something..without it turning into a huge project...LOL>.
..In other words..I make things alot harder than they should be I overthink it.>>...
Any imput would be appreciated and welcome..~:)
Peace..
Many Thanks~!
