Reading this threads makes me sigh greatly. Apart from a good moan off everyone I see no reason than other to delete every post here because no one has actually helped the guy at all what so ever!
The guy has an unstable system and has gone through the necessary process to fix it. He has been offered a pick up and repair service FOC but can't because of issues of him being away earlier in the post. Now this makes supporting an unstable system very difficult, even for us. So it takes a lot longer to achieve the final result, the stable system.
Why say this? Yeah its the luck of the draw if you get a stable system or not
Hmm you are looking at around 500 built a week so "so many" is really a very low percentage.
No this will not void your warranty.
I'm disappointed with the attitude in this thread to be honest
