If we're talking MSRP, it's probably my work laptop - they give us high-end machines though this one is older now and likely to be refreshed soon, so I don't know it's actual value today.
In terms of actual value, I've got some older video game hardware that might be worth a decent bit at this point. I don't know for sure, but some of it wouldn't even be easy to replace if it were to be broken.
