MSi GX740-235 Open Box from newegg

Hi.

Yesterday, during black friday, I noticed that newegg put up >one< unit of MSI GX740 ;open box; for $845.




I...
didn't think clearly through and just jumped at the price and the opportunity.
Even after tax, It was more than $100 cheaper than from Amazon.




But after looking at the spotty record of open boxes, I am very, very worried.
I thought that because it's the holiday season, anyone who returned it probably did it brand new.
But it seems that's not really it.

In addition to the possible loss of power cable/battery, I've read here in this forum that ppl need to to bios/vbios flashes, and a bunch of other things that an amateur can easily brick a computer.






....
So I'm extremely worried that the unit is just ;bricked; and will be DOA.


From the order record, it hasn't been packaged/shipped yet so I can cancel it right now without paying the return shipment.



What are the odds of me having a completely unworkable unit? Should I cancel the order? If, by chance, the item was bricked, can I call the MSI customer support and tell them it was DOA, rather than go through Newegg's customer support?


I am so, so worried.
