pc computer used under $500.00 for music only

Are you still looking for a computer for audio playback? I'm thinking about selling my Niveus Rainier w/daphile and a 2TB with 1100 albums on it.

Try to look to AM1 processors from AMD. Very power efficient. Get a small ITX case with built in power supply (power brick). It's enough to power it up and dead silent. For extra silence you can go for and SSD instead of HDD. 500$ is more than enough for new computer, not used.

A used Oct. 2009 Mac Mini is the ticket. Buy it on ebay for $375 with wireless keyboard , mouse and OS CDROM disk. Upgrade it with 16 gigs DRAM and a SSD from otherworldcomputing.com. Beats virtually all servers on the market if you supply DC power from a linear 18.5V supply. use Amarra playback software. I have won several best of shows using this configuration.

Been posting this a bit today.  How about a Raspberry Pi3 with HiFiBerry and Kodi or OSMC?
