IMO just open the case, buy a house fan and sit it right in front, it works wonders.
@Rockminer
Are you guys gonna keep making miners? I hope you guys keep kicking I love your little hobby miners.
i think they are after some one else to help them produce the miners.
As for the fan no idea about the R-Box, i think the thermaltake fan should do, for $11-12 for a fan and useless sink, not much of a loss if it didn't fit
