[New Build] Gaming Laptop ~2k$

Looking to build a gaming laptop for roughly 2k $. I know, laptops arent as good as towers for gaming, but my other requirements means I need to have a laptop. Size doesn't really matter, i have chosen a 15.6 because of price and I have been ok with it in the past. could go towards 17, but only if it is a worthwhile jump.

Timeline: now, a few of the companies are backed up about a month, so they are out of the question.

here is what I am thinking, from XoticPC

Questions:
Any additions i should consider? Upgrade the stock network card? the stock sound card? I am thinking about using it as a bluray player.
Any of the things that should be upgraded or downgraded? I have roughly 50$ worth of upgrade space, more if some things move around and would go up to 50$ over if worth it.

Thanks very much for the suggestions. Sorry to be dumb in this area, not my particular skill set, but want to learn more.
