I have to get the SD card and whatever is required to program it from Fedora 21 or 22, or buy one preprogrammed.

Pretty much any old SD card would do. I have this one: 


By far the most popular OS for Rasperry Pi is Raspbian (a Debian derivative). There is a lot more third party software available for this. But there is also Pidora (a Fedora variant) which I have successfully installed and tested.

I currently have an older Pi model B in service as my Bacula storage server, with an external 4TB USB drive for online backups, plus a USB enclosure that allows swapping drives to use for archival backups. Works great. Pi's have lots of uses.
