Sony Desk top PC's

Does anyone here have experience with Sony All-in-one  desktop PCs?

My wife is interested in buying one.....One of my questions after trying to configure a model at the website below, is that I would Like to put in an SSD drive (myself) in-addition to one of the regular drives.  Can these all-in-ones handle more than one drive and if so, can a end user add or replace parts without going to the manufacture?
