Can you share your favorite brands for the key components?
I had headaches at first because my DreamMachine's SATA port was faulty and had a poor connection to the HDD. I used 4 different HDD's to prove this, and getting Unifi support to agree with me was about impossible. They ended up giving me an RMA with a "yeah, buddy.. I'm suuuuure it's the SATA port." I had to pay to post the RMA for a machine that never actually worked.
The exchanged DreamMachine has been working quite well for over a year now though.
If I were to do it again I'd buy it from a reseller instead of directly from Ubiquity for better product support.
I went with Hikvision and wouldn’t look back.
