Is there an affordable all in one Flac burning appliance?

I am converting my very large CD collection to Flac.  I keep all my Flac files on a network Raid 5 array.  I am tired of my computer being tied up burning and there are a lot of steps to burn on my Mac.  Is there a well thought of all in one application via Raspberry Pi or something else that just burns CD's and does not do anything else.  I am always going to be buying CD's and I would love just to have a small device that could stay focused on ripping flac files for me.
