What else to raise on a home server for training?

Question

IT education

Good day to all.
Not so long ago, I started to get involved and study Linux systems and built my own small home server (Intel Celeron G1840, 16 GB of RAM, 2 hdd for 320 and 1000). Now he manages the network (distributes addresses, cuts ads), has samba, torrent, media server, mySQL server for some of my programs, web server and mail.
What else can be raised to learn and raise your level of knowledge? You can also do something for several cars.
Thanks in advance.
