It would be a shame to not share what happened after all so this is an update just for those who will land on this thread searching for a similar answer ... after my last message here I sent simultaneously, emails to all the available services of Thermaltake around the world in order to see who will respond after all ...
After one day the email I sent to the HQ at Taiwan got a response and I was seriously surprised to realize that they were asking for my address in order to sent me the PSU Cover ... No strings attached!!!
I must say that this was a big surprise for me after the frustration I went through to that point.
After I replied with my info they obviously sent the PSU cover without asking for anything in return ... and I just got it delivered on my hands today ....!
Thermaltake just won a devoted customer after that and my gratitude will be shown in many ways by letting everyone know on stream - on site and ofc on social media how I was treated after my request ...!
It is a shame though that no other region responded as long as this is what leads people to become frustrated and damages the company's authority when it comes to customer care, but Taiwan did by all means and this is what matters in the end!
So thanks also for "Guru" who was after all the one who led me to the answer and solution ... thanks man I appreciate that!
