I lost both of these and an Epox 8K3A+...
Actually, it was the Epox that killed both. I had the XP and Epox RMA'd, and the Duron was my loss (~$60). I figure, if I didn't have a water cooling setup, I wouldn't have messed with it, and it wouldn't have gone beserk.
The killing spree was not caused by any fault of mine, resulting in a leak... but it just up and went.
Three leaks, and no deaths. One leak lasted all day with the power on and got on the mobo, vid card, nic, and sound card. All survived after being dried and cleaned. And, yes, it was just carelessness.
