Synology DS918+ (plus) 4-bay NAS (16GB RAM, diskless)

Selling a Synology DiskStation DS918+ NAS in great condition! It comes with the box and all original components. Upgraded to 16GB of RAM for virtualization/hosting. Original 4GB kit of memory included. New(er) power supply. Bays' keys, Ethernet cable, and original packaging included. No drives are included (diskless). I've used it for a few years without issues. I've had to upgrade to a similar model with more bays for extra storage but never had issues with this one. It ran with up to 18TB drives and with a full load of 4 drives at its peak. I've replaced the power supply (common for this model I believe) with a new one and upgraded the ram to 16GB (up from 4GB).
