I did use several smartups ones at 1500VA, and the metal construction was full metal, passive cooling on the interior with ample empty space, nice battery connections. At work we have larger APC racks for server backup and so far we didn't really experience problems. But the larger enterprise sector seems to be quite different than the consumer sector. As I wrote before, I'm not powering servers and I actually went the route to place a smaller ups close to each load individually to avoid single points of failure and also avoid complicating central cabling. Just because I'm going for smaller sizes it doesn't mean I'm trying to cheap-out, quite the contrary. For the smaller power lineup, APC definitely is not better than cyberpower in my eyes. In fact, the back-ups rs line is almost twice as expensive as cyberpower and I'm not really satisfied at all. The cyberpower unit has actually sine wave output for the same cost, upregulation works even at very light loads, and it's also a much quieter unit compared to the APCs when idle (when driving load both units buzz loudly). When having several in the same location, this does make a difference. Opened up, both have the same quality of construction. Which is probably adequate, I guess. But having a metal shield around the battery would have been sensible.
