The spec looks OK for the money. I'm not into video editing, so I don't know whether there's software available to take advantage of your dual core processor, but you've certainly got plenty of HDD capacity for that job.
Are you allowed by your company to tweak the spec? If so, I would try to get an on-site warranty, rather than RTB.
Whose antivirus software is it preloaded with?
The only other thing to question is the built-in speakers and the fact that the spec doesn't seem to include a sound card (so sound is probably on-board). If good surround sound is important to you, then a high spec sound card with 5.1 speaker setup would be much better.
