I have a Shuttle 9.0 on the way to me. I plan on racking it in my SKB 3u case. I would like to get a 1u compressor also. My question is, will I have an issue with heat? I wanted to get one of those slick 1u rack fans from www.rackfans.com, but if I get a comp I will have to get a 4u case. Any advice?
