Hi, i'm just replying to say this works ok for me.
I've just built a 78LMT-S2P + Athlon II + 4GB RAM + 2x500GB @ Raid0 (5400RPM haha), tried that with XPenology 5.2 and after use the Shutdown script and give chmod +x (execution permission), this works and now i can wake-up my NAS from "Synology Assistant".
I will buy a Synology 2-or-4 Disk Hardware, they deserve, because the software is impressive and the system is incredible.
Thanks.
