The lazy home sysadmin's dust-free solution

[Ranko Kohime]

I've been running this config for a while, and I thought I'd share my dust-free solution, and the results thereof. These results are from my offsite backup server.

I put it in a plastic bin. With no ventilation. I know, I'm a horrible abusive monster who should be given a restraining order from silicon. :D

Now granted, there's about 4x the air space in the plastic bin that the case takes up, and the system is run in a basement which stays between 60-70F year round, but it's still basically static air. The cables are routed in through the lip, but the lid still closes completely over the cables, and after 1.5 years, still no appreciable dust in the system, which leads me to conclude there is negligible air movement into and out of the bin.

Temperatures at idle.

Code:

dev.cpu.1.temperature: 37.0C
dev.cpu.0.temperature: 36.0C
ada5 36C WD-WCC4N0XXN69Y WDC
ada4 38C WD-WCC4N7ESTL3S WDC
ada3 40C WD-WCC4N0XXN13L WDC
ada2 41C WD-WCC4N7ESTN72 WDC
ada1 39C WD-WCC4N0XXNC8K WDC
ada0 37C WD-WCC4N7ESTK8K WDC

Temperatures after 3.5 hours of scrubbing, so probably stable worst-case temps (50-60% CPU load because Celery)

Code:

dev.cpu.1.temperature: 43.0C
dev.cpu.0.temperature: 43.0C
ada5 39C WD-WCC4N0XXN69Y WDC
ada4 42C WD-WCC4N7ESTL3S WDC
ada3 43C WD-WCC4N0XXN13L WDC
ada2 44C WD-WCC4N7ESTN72 WDC
ada1 42C WD-WCC4N0XXNC8K WDC
ada0 40C WD-WCC4N7ESTK8K WDC

After 1.5 years, no hardware failures (save for USB drives, but that is a problem I've been fighting for over a year on my home system as well)

Feel free to tell me how wrong I am for being lazy in this way. :p

With those temperatures, laziness approved.

@ garm: hold your horses ;) Let us have a look at some pictures first ;)

Will do next time I'm at the offsite. So probably this coming weekend.

I made a small gallery out of it, enjoy.

Why have you put the extra TP-link Ethernet adapter?

A bit of paranoia regarding Intel CPU's and NIC's. Not that the paranoia has gone away since, but it has been turned into nihilism with more recent reports of the NSA's abilities.
