Now here's the final breakdown

of the finished conversion.
From the outside (top). I added a cordless handset for your comparison:
You see that I mounted the 8cm fan inside of the case, not as a hump on the outside. You'll see soon that this caused some extra work for mounting the fan. If you want to protect your fingers and avoid breaching FCC regulations you'd better put a fan grille over the air intake. A golden one wold certainly look very nice
From the top, with the lid just shoved back as far as it needs for dismounting/lifting (approx. 1cm):
As you can see, the fan does not move, because I could not fix it to the case-lid.
From the top, lid lifted off. You can see the cardboard construct to mount the 8cm fan directly over the CPU. The green line indicates where the cardboard was glued to the chassis. In the area outlined in red the cardboard just lays on the drive-cage (or what remains of it), it is
not glued to it. Otherwise it would be impossible to dismount the drive-cage. The 8cm fan just bearly fits between the rear of the chassis and the drive-case. So there is not even 1cm room to maneuver should you try to mount the fan to the lid of the chassis. This way you also avoid unplugging the fan from the mainboard should you take the lid off:
What I didn't mark in this image is the cutout from the drive-cage to the left of the red area. This was just to give the two stacked HDDs some headroom under the drive-cage for better ventilation. Remember the 5cm fan in the back now sucks air into the case and blows it directly across the HDDs for optimum cooling.
Taking off the drive-cage you have a clear view of the stacked drives, wedged between the left wall and the mainboard with some rubber foam and a rubber tube for optimum silencing:
Next up is a clearer view of the drive-bay, made from cardboard (1.5mm thick). It makes sure both HDDs have a defined gap between each other and the case of around 3-5mm to let air flow through and around them:
The distance between the mounting threads of each drive is 3cm.
Now the final image shows you what I "mounted" the new cardboard drive-bay on:
I cut the pieces of rubber tubing in half to reduce the hight. And I must admit that I didn't even glue those pieces to the bottom of the case. That's because I just planned to operate the Nettop in a horizontal position only. And I wanted to avoid drilling another set of holes into the bottom of the case to mount the drive(s) with rubber grommets.That would have been the engineer's favourite, but alas: I was a little tired of hacking and cutting and drilling into this beautiful little machine...
That's it, folks! Cardboard and rubber can turn your measly screaming Nettop into a silent 2TB home server in no time
Btw.:
Here is an interesting article about Nettops as the next big thing in data centres.
And
here are all the images I took at this conversion.
