1) even though the method has a high success rate in general, there's no telling how a reseller behaves. Some, like Amazon, have begun treating EB as DNA and ask for PR even though no crime has been committed whatsoever; Samsung claims it can be 100% sure their goods were packaged and shipped properly...

2) the CPU itself weighs less than 100 grams, the decorative box around it actually helps you in performing the SE because it hides the CPU from sight.

3) it totally is

Perfect, thanks for your answers. I will try to do one or two legit orders before eb my stuff

I can tell you it all depends by the box they use as well. I did an SSD and it went perfect because could not be seen from the outside, while some ram came into clear plastic that could have been seen from everywhere. For the CPU some come in a box where it can be seen from the outside..
Basically it really depends on many factors, and everything can be understood with a bit of research before the SE. Hope this helps
