I got one cheap off of eBay, with a year of warranty left and seal intact, but the guy said he was selling it because it'd frequently freeze at boot. So far I haven't had any sort of issue, although I haven't had it on for much more than an hour or two at a time. As it is, it's in a fairly open and somewhat well-ventilated area, but is there anything else I should be worried about? I know Jasper boards are some of the most RROD-proof, but I'd like to take whatever precautions I can so I don't have to send it in.
