Dell are awesome, and that's coming from someone who deals with over 400 of the things daily
Now, is it difficult? depends. In your average pc? no.
In some Dells? yes.
What model do you have? I need series (Optiplex/dimension etc) and what size (Desktop, full desktop, compact, etc) but in the end, it will likely be a 2min job [img]smile.gif[/img]
