Pros: When working the HPz420 workstation is awesome. I previously had one where I worked and it was a work horse for heavy graphics, engineering programs, etc.

Cons: My Z420 gave me 5 months of use and then died. I had used it to write a few resumes and check emails. This computer was not used as a gamer or to run any other resource taxing programs.

Overall Review: Do not buy this. Save some money and buy new, it will pay off later.
