It sounds like a fantastic PC.
You wouldn't like a straight swop with mine would you?
Seriously though I've seen the posts you refer to and even commented in some of them. You've had 2 Dells that you were quite happy with and hence you went and bought another. Fine, good for you and I hope all goes well.
Some of the comments that others have made are just rubbish as I'm sure you realise. And I've no doubt when these same people see your posting they will have to comment yet again. In my humble opinion Mesh are no better or worse than any other big PC manufacturer. I feel sorry for those that have had problems with a PC from any company but what they forget is just because they are unhappy they forget about the many others who are happy with their PC and make such comments as "don't buy from them they are rip of merchants" or the like. And if you try saying they are being unreasonable because their PC broke they accuse you of favouritism.
Anyway I wish you luck with your new PC and hope it will give you many happy hours of trouble free pleasure.
