Seagate HDD spacing of PCB and ReadyNAS Duo Cradles
I have a question regarding the space between the HDD NAS cradle and the exposed Seagate HDD PCB.
My electronics knowledge is high (I've been building complex projects for more than 25 years) but I'm not sure whether the (barely) 1mm tolerance between the drive's PCB and the metal cradle chassis is enough. There are exposed PCB tracks on the HDD's PCB so I'm slightly concerned about shorts or other issues due to the close proximity.
I'm probably worrying about nothing (after all, why on earth would Seagate leave something like this so exposed?) or my concern may be valid. In a perfect world I'd drop a thin piece of plastic shield between the two and get on with things - but I don't have thin high-temp plastic lying around!
Any thoughts?

- It appears that the newer drives by both Seagate and Hitachi in an effort to protect the components have turned the circuit boards over. WD and Samsung may be doing it as well, but I don't have any samples. Previously the components were exposed, but the boards were recessed more. However, it also appears that the flat head screws used to attach the boards would protect the circuit boards. They don't quite touch.
It is a close margine, but I have had 8 to 10 of these style drives in service for a year and have not encountered any problems. I have had two drive failures, but they were more disk related, the drives were throwing errors, not an electrical short. - They power up just fine, cheers.
