rackmount

I came across these two items of non-integer rack unit height:
1. This rack mount kit which seems to be trying to make the best of the slightly-taller-than-1U form factor of the Cisco ASA5505.
2. This 1.5U Server Case that espouses the merits of a case height between 1RU and 2RU.

My questions are as follows:

A. (1) seems to protrude 1/8 RU above and below the rack unit it is bolted in. Is there any way to make use of the 7/8 RU remaining above and below? Or would using that bracket effectively consume 3 RU?

B. Are there any gotchas I should be aware of (like rack rail bolt patterns not working out, etc) when I consider one of these non-integer RU server cases like (2)?

Where can I buy a good rackmount workstation?

We have a product which consists of a GUI program and all the hardware goes in a rack. Our department bought a rackmount server for the first unit, but I dont think this is adequate for applications that use graphics (correct me if I'm wrong - we bought a Dell R710). Could you tell me of a good… >>> More

Rackmount temperature/humidity control

as seen on Server Fault - Search for 'Server Fault'
This may seem like a strange question because it involves a non-traditional approach. What I'm looking for is a standard rackmount cooling/humidity control module. The idea is to build a portable server rack (in a case) that can be deployed to the field but limit the cooling/temperature control requirements… >>> More
