I just succesfully added a extra dim in my RN426 readynas. I have opend the black cover and remove the 4 black screws from the metal frame and you can get to the mainboard 🙂 You can slide this side open. I saw 4 memory slots. I have added the same memory that was already in it from Transcend the TS512MLH64V1H. I paid 39,- euro's in Holland but you can get it for arround 26,- here also.
