After 6 months in operation makes annoying clicking sound, the fan wobbles so much, making coil wine noise and hitting the sides of the enclosure.

Overall disappointed in this product - the first one we received was shipped with missing cables (according to the manufacturer, their QC is very good and this is unlikely to happen, but still) and the replacement works well but has a strange and constant clicking noise

After a few days of use, the power supply started making LOUD metallic clicking, probably the fans hitting something

The first one I got made a noisy clicking/chirping/ buzzing noise
