APC Smart-UPS SMC1000-2U Rackmount UPS, 1000VA 120V, 2U LCD, NO BATTERY (Open Box)

Heads up: This is for the UPS *only*—NO BATTERY INCLUDED.

It's an APC Smart-UPS SMC1000-2U, a 2U rackmount unit with a nice LCD screen.

It's rated for 1000VA / 120V.

This is an open-box item; it's new but the box might have some shelf wear.

You'll need to supply your own batteries, but if you've got some laying around or want to save by buying them separately, this is a great way to get a high-quality APC unit for cheap.

The brains of the system are here, ready to go.
