So I ask: Is there any hardware product whose sole purpose is to receive 
an ethernet cable and record everything internally? I would leave that 
device for a few days, then collect it, extract the data, and run my 
analysis through Wireshark.
    

There are, I think, a number of companies that sell devices such as 
that, e.g. Solera (found by going to the "Sharkfest '08" page from the 
Wireshark home page, and looking at the list of Sharkfest sponsors):

and NetScout, as mentioned in another reply:

	http://www.netscout.com/products/infinistream.asp

and (if I'm correctly interpreting what the devices do) Network Instruments:

	http://www.networkinstruments.com/products/gigabit/GigaStorProbe.html

and NetQoS:

and so on - see the list of vendors of "network monitoring and 
management software and appliances" at

I don't know how much those devices cost, though.

  

Thank you all for your responses. Unfortunately, all of those capture systems are for high end corporate IT solutions, as if I wanted to capture the entire network or something like that. I just want to capture a device, just one. So all I need is a small capture box, not a rack mounted server.

So I guess the solution is, as was proposed, to get a small cheap laptop and bundle that to the customer's location.
