Vita, did you buy from the dell outlet or another vendor on the bay?. How much did you pay if you don't mind me asking?
I paid £1.3k from a vendor on eBay who sells these. I think he gets them from the outlet to sell on. My box was fully sealed and hadn't been opened at all. He's been ok and guided me through the process of contacting dell etc
I'd start laying it on thick how you need this laptop for work etc, ask them perhaps if there is a replacement system available... (hopefully with higher specs)
Sounds like the same seller I had, 37k feedback.
Update: After a 2 week wait due to dell not having my motherboard, I now have a working machine. Engineer came today and installed the board, all went smoothly. I will not be updating the BIOS, his comment on it was that it's rare for the motherboard to die during a BIOS update, although with dell not having any in stock it does beg the question why. Funny thing is, now in the BIOS my machine is showing as Alienware 17R4 lol. Strange, but it will have to do. I will probably do a small review about the machine later on. So far impressions are that it's good.
Maybe I might painfully wait a bit thentry them both. I went for vive. roomscale is epic plus wireless adapter coming in a few months.
