Quick verdict
The APC SRT3000RMXLA Smart-UPS SRT 3000VA Rackmount UPS is listed at $214.34. That price reflects two important conditions: the unit comes without batteries and is pre-owned, re-boxed, with visible wear. If you can manage battery provision separately, you get a 3000VA/2700W UPS platform at a notable price. If you need a ready-to-run unit, this isn't it.
Who it suits
This fits a rack-focused shopper who can manage the extras. The product name points to rackmount design, and the specifications put the unit in a 2U rackmount form factor. A 2U footprint fits well in network racks or compact server cabinets where rack space is tight. If your setup has an open 2U slot and you have time to source batteries, the unit becomes more interesting.
What stands out
The $214.34 price is the first thing that stands out for a UPS in this capacity class. The condition caveats are part of that picture: the front bezel retaining clips are damaged and the rear USB port is defective. If you can live with those issues, the price is the clearest draw. The capacity class is also evident from the product name, so you know what you are considering before you look deeper.
Meaningful trade-offs
The most significant trade-off is that the unit does not include batteries. You will need to provide your own before it can serve as backup power. The rear USB port defect is also a stated problem on this specific unit, so a USB-based management path may not work as expected. The damaged front bezel clips are more cosmetic but still affect how cleanly the unit fits in your rack.
What to know about the APC SRT3000RMXLA
APC SRT3000RMXLA Smart-UPS SRT 3000VA Rackmount UPS

This pre-owned, re-boxed unit is the 3000VA/2700W rackmount model in the Smart-UPS SRT line. You are buying the UPS body rather than a complete backup system. Choose this UPS if you already have compatible batteries or a budget for them, and if you have a 2U rack slot available. Skip it if you need out-of-the-box protection or if the condition caveats are dealbreakers.
Bottom line
The APC SRT3000RMXLA pairs a useful rackmount platform with a long list of condition caveats. Buyers who already have batteries or are willing to source them, and who can accept the stated condition caveats, may find this a worthwhile option. Buyers who want a plug-and-play UPS should keep looking.
