I have a ROCK server built on an Intel NUC i5 with 128GB SSD and 8GB RAM.
Cost me about $460 for parts and will come with Roon ROCK server already installed and updated for you. Does not include Roon license of course.
Always worked perfectly. Just not using it anymore so no point in it sitting around.
$350 plus actual shipping + 3% for paypal
I’ll throw in a USB>Ethernet adapter if I can find it and a couple of Cat 6A Ethernet cables.
