This is MY opinion, and MINE, ALONE; In NO WAY!!!! is this sanctioned by ET.
Now: I would be extremely careful about getting involved in a transaction of this nature.
First off, I don't think anyone, other than Bill Gates, has that sort of money to spend. Also, this should not be the sort of thing that would be auctioned off.
And, who is supposed to pay for the dismantling and shipping costs?
I'd be interested in knowing the location of this room, as well. If nothing else, somebody in the UK should be able to validate the location, and the items.
Also, the seller may be someone to be extremely wary of. However, I need to check at least one or two sources, first.
Right now, there are no bids, as most people checking eBay would have to take out a mortgage before they could pay the listed price. For me, the quoted price is 7 years salary.
Needless to say, I won't be competing with others on eBay.
