Well, I got my Octominer case in, and I found a huge problem. Its supposedly a 4u rack mount case, but it doesn't fit in a standard 19" rack!..its over 22" wide! Oops.
So its useless for hosting in any datacenter, unless its a mickey mouse one that just uses shelves, vs proper enterprise racks.
Also has some very nice Delta PWM fans, unfortunately the PWM and sense leads are literally snipped off, so fan speeds are not controllable. Grrrr
