No, that is
barrel distortion from the camera lens, you can see the same bowing but slightly less extreme on the bottom edge of the monitor. It's straight and just an FYI, these Northgates and many others would take a car driving over them to bend. Their back plates are very thick steel. That other warped board might not even be a Northgate and it's possible it was a plastic case/back plate even if it was. This is a different board entirely.
Oh wait what am I doing!? Yes it's horribly warped, don't anyone buy it, stay away at all costs please!
