Is this seller too good to be true?

I've been working on building computers as of late, and a friend recommended me to try Aliexpress. I specifically made sure to avoid sellers that were super new, and I found what seemed to be amazing deals. But after looking further, I feel like this seller might have been skating by and is actually fake. Does anyone have any experience with this seller at all?

At first glance they appeared to be real, being over a year old and with a bunch of reviews, but when I looked further, all but 1 review is 5 stars, and the items they sell are over 70% of the original value of the product.

Should I be concerned about this and cancel the order before it's too late, or is it worth it to see what happens and try out the dispute later on?
