Like anything else, it depends on your needs and wants. Not everyone requires one. I find that having a central file server has made life much easier. I have a laptop and rather than having a ton of external hard drives to hook up when I get home, I just have to join the wireless network and I can backup my files and access archived files. I use it as a network file backup device to store old projects, make daily and week backups, transfer files between computers in the house easily, and so on. I also make ISOs of all the software I buy and archive them on the server for safe-keeping. Additionally, I store disk images of all of my computers and my client's computers, plus VMs. Say my wife's parent's computer gets a virus and croaks, and they lose their backup discs...I can simply burn them a copy of their disk image and restore their computer in under 30 minutes.
I also use it with my Xboxes for multimedia. I have a modded Xbox on every TV in the house. The file server holds the multimedia and streams it to the Xboxes. Photos, music, movies...all are stored on the file server and can be played back on any Xbox or computer in the house. Instant access to all of my multimedia and my wife can still watch a movie or listen to music even if I take my laptop to work - plus my laptop's drive is free to store stuff other than large multimedia files. I don't have to keep any CDs or DVDs in my living room, it's spotless because they're all on the server and the discs are tucked away in a cabinet.
But, that's not for everybody. Most people just use DVD players for movies, a stereo or iPod for music, and have a USB thumb drive or backup hard drive to store their files on. It's also not always about practicality...this is Anandtech and we are geeks after all
