$30 DIY IsoBox

[cooker]

Thanks for sharing, very nice design!

[rolo95]

Hey looks awesome man, can u post list of materials and a plan or something to follow the build?

It will be interesting if you have any overheating problems.

[private_stock]

Yeah, from what I see it looks like it will cause major heat issues. Hopefully you've taken that into account or got lucky!

Long live DIY.

Cool!

Is that open or closed-cell foam? I would think that using mineral-fibre would be better acoustically, though maybe more expensive.

How is the low freq. noise reduction?

Well it has been 24 hours...The temperature is the same as before I put it in the box (actually 1 degree lower). The key to this whole design is the fan I put on the exhaust side. I just pulled a computer fan off an old computer and powered it with an ac adapter. The air moves very well. Keep in mind this is a budget model, I'm sure you can find better foam. The foam high density urethane from a craft store, on sale for $4.99 a yard. The server is not sitting on the foam directly, it is sitting on legs (little pvc pipe couplers)

As for the DB reduction. The difference is amazing. I wish I had a more technical description but... it went from a shop-vac to a microwave.
Please pardon my crude drawing!

How are your hard drives mounted in the chassis?

An easy way to buy a few additional dB is to vibration isolate them... suspend them within the chassis using elastics or similar.

patent it, cool idea


I just moved mine in the other room

[shuttrbg22]

Well I can't say i've ever heard the hard drive, really hard to hear anything over the two 13,000 rpm fans. The two server fans are 60db each.

And to those who WILL ask "Why dont you put it in the other room, buy a quieter computer, change the fans, put it in the fridge, put it in the closet, etc etc." The answer is , cause it was loud and free.
