APC Back-UPS Pro 1500VA Battery Backup and Surge Protector
$229.99
A consumer-grade sibling of the Smart-UPS at a third of the price, and the difference is where it matters: 900 W against 1000 W, and a much shorter warranty on the electronics.
Full details →Who the Synology DiskStation DS923+ 4-Bay NAS Enclosure is for
Buy it if: Offices needing four bays, ECC memory and a route to 10 GbE later.
Avoid it if: Media servers relying on hardware transcoding, which this processor cannot do at all.
Who the APC Back-UPS Pro 1500VA Battery Backup and Surge Protector is for
Buy it if: Workstations and small NAS units that need sine wave backup without a rack-grade unit.
Avoid it if: Server closets, where the shorter warranty and lighter build are a poor trade.
