Home Server Distro Recommendation

Hello, I have just started to use Linux a few weeks ago, since I am setting up a home server. I have some specific functions that I want it to perform, but I cannot decide which distro to use. I tried Ubuntu server already, and had a hard time configuring it in the CLI, but that does not scare me away. I am fine with learning and do not mind to use the CL. My requirements, at least, will be these: 1.) File sharing (is Samba required for networking the server and Windows clients, or can I use just SSH or a virtual environment?) 2.) Torrent server - I do not want to use Transmission, so any distro that supports rtorrent or Deluge will be better 3.) Media streaming - I have a PS3 so live streaming to it would be a great function to have 4.) Remote management and access I already have a router that acts as DHCP and assigns static IP addresses, so I will not need to assign my client computers their static addresses as it is already done. Also, I do not need to host websites or a firewall on the server. I have been doing much reading in forums and tutorials on several distro sites, as I have only used Windows before. If you ladies and gentlemen could help, I would like to know your recommendations about the OS type I should use for optimizing my requirements. Thank you, have a good day!
