I believe Synology is taking failed NAS boxes, adding the resistor and shipping them back out!!!
Don't know if they are fixing dead boxes but they are definitely repairing and sending out used boxes with lots of hours on the clock. I requested an 1815 replacement before mine failed and received a used unit with the resistor. The case was beat up and there was hair and dust inside of it. I called and requested a new unit. They said there are none left. I returned the replacement and soldered the resistor on myself for about $3 and 15 minutes of my time. First thing I did on the 1815 was add a CPU fan and added vibration dampening to the cheap rattling drive cages. Wondering if the fan extended CPU life. It dropped the temperature by 20-25 degrees.
This is the last Synology product I ever buy. Was hoping the high price was justified with solid software and better customer support. It's overpriced junk and updating on day 1 is akin to playing Russian roulette. Think about the opportunity cost with $1000. With a couple hours of research, you can build a far more powerful NAS for less money then when a part dies, you replace that part.
