Here is a recycled Dell Optiplex 755 which died. Black filament, MG47 material according to the stamped info on the pieces of plastic.
Started from the initial beige of the previous Dell from 2000, then gray mix, then black.
No laughing at the weird funnel, please.
Hopper cracked and needed to glue and clamp it later.
Final result. Very pleased.
MG47 is good stuff!
How'd you shred/granulate it?
My usual brutish ways. First with an electric wood chipper (new from Home Depot), then shears and a small coffee grinder from Walmart.
All steps sucked in different ways. Woodchipper - scary, shears slow and my paw still hurts then the cofee grinder slow so I do not burn out the motor.
A good shredder would be nice 
Precious Plastics has DIY instructions for motorized shredder which makes direct pelletized material if you want to.
They say that if you do a lot of scavenging etc you can build it for less than 200$. But you'll need to do quite a bit of scavenging for that.

I am looking at it, not sure if I can scavenge what is needed. What I am looking for is a kit that I can assemble, similar to the Filastruder and Filawinder.

The scary woodchipper http://www.ebay.com/itm/Sun-Joe-14-Amp- … SwZ8ZW5nLx spews some nasty shrapnel (yes, I did have safety glasses on), but it spewed a few sharp edged ones that easily penetrated the plastic bag that I was collecting the output into.
That prompted visions of my sweaty hairy legs potentially being coated with blood. New updated collector will be a plastic bucket to contain the shrapnel.
If the plastic fed to the Filastruder is too big, it will eventually crack the input funnel and put unnecessary strain on the motor.
The filament is good, I just printed two spool sides to attach to a toilet paper core. Pics will come soon of the wonderful creation.

I don't think it'll happen - there's just too much liability involved, unfortunately.
I was afraid you would say that
I need to watch the video mentioned https://preciousplastic.com/en/videos/build/shredder/ with sound, I wonder if they sell the laser cut parts kit so I could assemble it.
"Reinforced" hopper. (apologies, Tim, was too lazy to print another one)
First pass from woodchipper. Next step is to cut bigger pieces using shears, then use the coffee grinder.

The Filabot grinder is sweet. but at Well over $4k that is a village purchase.

Too expensive for me. At 1/10th of the price, maybe, but so high, cannot afford it, unfortunately.
Yeah, I'd love to recycle my failed prints, brims, rafts, etc... Sadly, there's no reasonably priced shredder out there. Precious Plastic's design looks ok, but I doubt I could source the blades for <$200. Not to mention the other machined parts. Not all of us have CNC mills and metal lathes sitting about. I could likely find/build the rest, but those parts require more precision than I can manage with the metal working tools I have available.
Even if you share a grinder, you have to be careful about contamination from other people's jobs and mislabled/sorted bits. Getting some ABS in a PLA run wouldn't work so well, for example. If your design allows for good cleaning, it's less of an issue.
My brutish setup (woodchipper, meatgrinder and coffee grinder) works, but it is time consuming and the manual steps (shears) are physically painful.
The cost was about $200, but I wish I could improve on it.
The filament results are good and the satisfaction factor to recycle the old computer cases is awesome.
