I'm graphing this type of data, but it's too early to draw firm conclusions. I was mainly concerned that the upper, rear units might not fit within my desired thermal envelope, but so far it hasn't been an issue at all. This might make it into our follow-up post, which is intended to explore the design decisions behind the chassis. If heat or airflow did become a problem, we could add fans to the chassis (either in the intake tunnel or along the exhaust vent). The ideal solution is probably to also attach a chimney to the rear of the rack, but so far it hasn't been necessary.
