I have been using an NSK2480 for 5 years. The 380PSU is still solid as a rock. Handling 3 internal, 2 external drives + DVD drive, discrete graphics card. Is roomy, not a small footprint but well ventilated and excellent features. It does not have a remote or built-in ir that the fusion series have.
The links that came up do not look like the same case, so not sure what the confusion is. I thought the NSK2480 was discontinued by Antec and that they were only selling the fusion series but not positive.
