I want to up the reliability further by getting an ITX motherboard & 1U case designed for it, and do a mirrored drive. I've been impressed with my ITX suitcase's low power consumption and low heat (and low noise, but that isn't such a big deal for a co-lo).
I can buy a Travla C146 1U case locally. Stats: http://220.127.116.11/products/Travla/c146/C146.html
Does this seem reasonable? Any geeks want to give me input before I start buying parts? Thanks.
