Hi Terry
Watch
this video, the first video as you scroll down the page, for a very concise walkthrough of how to upgrade an HDD in the machine you're looking at.
Personally I would be happy to do that but you may not. If you are then great, if not then you might want to consider making the full investment immediately, considering the additional cost of an SSD, and the tools required, should you want to do it in the future.
One thing to note, it clearly states that
"Remember that if an SSD was not installed in these models at the time of purchase, it will not have the needed connector to install one later." so that might make your mind up for you anyway...
Hope that helps
Thanks
Mark
