I have actually owned this desktop, and replaced the hard drive with a larger one. It is actually a very easy task, and instructions on how to do this should be in your user manual. If you no longer have your user manual you can download a PDF copy off of Dell's website.
Your reference of 120,000 MBs did throw me off a bit since hard drives are rated in GBs. There are 1024 MBs in one GB, which means if you need 120,000 MBs of storage capacity you would have to at least replace your hard drive with one that has 117 GBs or more.
This desktop accepts SATA hard drives only, and I have made a few suggestions below. I hope this helps!
