I contacted a few retailers and wholesalers around the world, quietpc was one of them iirc.
Is this product available in the US? If so, what is the street price?
Hopefully they will be in a short time. Endpcnoise already received the pricelist. Pugetsystems were looking for something that would completely silence the drive - I am looking into possibilities here.
Regarding street price, well, without knowing the tax and duty system in the destination country/state I am not able to tell, but I can tell you the MSRP is 10EUR for the single, 21EUR for the 3pack and 25EUR for the 4pack. These include VAT. Since - If i'm not mistaken - there is no such thing as VAT in the US, the prices should be similar or a bit higher in USD. All depending on the amount bought by the wholesaler/retailer since transportation cost is quite high.
My concern would be with the suspension material -- it looks like a foam product of some sort, and these tend to dry out and fail in relatively short order.
The suspension material is half synthetic foam rubber that should not age/dry out/loose it's elasticity - at least not as rapidly as plain rubber. As Gabo and Faugusztin mentioned before, the same material was used in the previous version and there is quite a few of them out there for 3+ years. Sure, there is a bit more rubber in the older version, but there the rubber was stressed a bit more as the whole assembly was about 1/2" - 12mm narrower than the 5.25" bay so it had to be stretched quite a bit to mount the assembly at all. I chose to lower the amount of rubber to cut costs - without harming functionality, as the rubber itself is one of the biggest numbers in the total manufacturing cost. Providing replacement rubber kits is sure a good idea though!
If the airborne noise of the suspended drives are low, then simply replacing one or more of the CD drive bay covers with a mesh screen will automatically generate airflow, assuming you have at least one exhaust fan in the back. Even a wee bit of airflow is enough to drop drive temps considerably -- they're typically <7W idle and these days, not more than ~10W max. For a green drive, it is a couple watts lower.
I am working on a simple meshed frame that fits in two or three 5.25" slots, that would simply fit the installed killers and could as well hold a fan if needed for cooling 7200+rpm drives. It will hopefully be available soon too.
"green" drives do not really need extra airflow if there is a free 5.25" bay above them to dump the heat to - this is my private opinion
- especially after looking at that google document.
