Well the only thing I can think of is my computer. It's mined 5BTC so far. It has a avg hash rate of ~920 M/H. From what I've read on these forums my "IRL" credit is on the line too.
Real life credit is not on the line. Not too many people are taking legal action, even if the scam is in the hundreds of thousands of dollars.
I assume you would only be shipping the video cards - not the entire computer. A couple video cards might be enough of collateral for a 5btc loan, but not for me. I would need something I could easily sell should you default on the loan.
