Actually, there is a bit of a problem with this partition scheme (but it's not the memory, which is fine. You've allocated 571 GiB for / (root) but only 17 GiB for /home, which is possibly back to front from what you intended.
As you can see there's only 12 GiB used on / and it's likely that it will not get much larger than this unless you are going to install a huge database program or just about every other program in the repository. On the other hand /home is where you be putting all your data (/home/username) and 17 GiB is a little small.
I would suggest you boot off the LiveCD and use gparted to adjust / to be about 25 GiB and use the rest for /home.
