AMD 4124P is just a 4c CPU that’s slower than a MacBook Air, and retails for only $149 USD.
16GB DDR5 costs around $40 USD.
This thing doesn’t even come with any storage! And expansion is limited to start with!
Subtracting the above — 549 - 149 - 40 = $360 for mb+case+PSU.
This server has just a single RJ45 (even then it’s terribly outdated at 1Gbps), only a few USB3 Gen 1 (5Gbps) ports on the front, and the USB on the back are actually just USB2.
Sorry, but in what world is this MB+case+PSU worth $360?
$549 is less unreasonable than the prior $609.99, but nowhere near a good value.
