SYNOLOGY DS718+ Teardown

소개

Here's a step-by-step tutorial to dismount each piece of the NAS until you reach the motherboard.

'Note: the interest of this tutorial is however limited.'

Indeed, most of the components that a user can be brought to add or change are now accessible directly, without disassembly (storage disks, memory expansion).

*This is a step forward, the previous revision must be completely removed to change a single RAM array.

Only the memory stack on the motherboard and fans remain inaccessible directly and require the disassembly of the NAS described in this tutorial to be changed (whether they are HS or replace them by better components).

The dismantling time is estimated at one hour (but with photographies). That said, it is certainly achievable in 20/30 minutes.

The photographs were taken with an iPhone SE, using a portable LED studio.
