Plan A was to locate the server in a large utility room. However, it turns out that in the summertime, that utility room hovers at about 30C (86F). This is much warmer than I'm comfortable with. So, on to Plan B which is the air conditioned office area which is still dusty, but much cooler.
To host the server in the office area, we need some kind of box to house it in that can filter out dust. In my research, I found that the standard for this rating is IP 54 or NEMA 12. Those are two different standards that say the case makes the computer safe from dust and light splashing.
I did some research and here are the best options I found.
- APC NetShelter CX. This is a nice looking cabinet that is sound proof and comes in various sizes. The smallest of these is an 18U box that is about $3800CDN retail. The dust filtering option is and extra $100 or so. I think this would be my choice in a standard office environment because of the looks and the soundproofing.
- Tripplite SR42UBEIS. This is a 42U rack that looks like a server rack. It's large and not pretty but gets the job done for dust protection. However, there is no sound proofing. So, this one seems best suited to a dusty utility area than within an office. You're looking at about $2300CDN retail.
- Dust Free PC. This company has a wide range of dust enclosures for computers and servers. The most basic enclosure for tower servers is about $600 plus shipping. Versions for rack mounting start at about $1500 for a 10U rack. These are not as pretty or sound proofed as the APC NetShelter CX, but they look very functional.
