Well, you ordered it, so hold off on that buyers remorse. So well done on the upgrades to processor and graphics card. I wouldn't get a machine like this without those. You'll simply need to manage your hard drive space. The main thing is media will take up space: music, movies, photos. You can use one large external drive, a JetDrive, or SD cards as those get to take up lots of space. Just be organized and you'll be fine. Down the road, you should be able to pay for an SSD internal upgrade if you want.
