I never had a Pi before and want to get me a pi-hole for my network. Is it possible to run pi-hole on a pi and some other applications like:

• That one that emulates chromecast? MiracleCast?
• Something that emulates a smarttv and let me stream YouTube/netflix or just from a normal web browser?
• Or just something that lets me stream Video files/streams from my pc with an application other than miraclecast?

The pi would be connected via Ethernet cable with the Network and with HDMI with the tv.
