They do make good reviews, but they just never seem to point out the big niggles with Antec cases, it is probably because they are not allowed to.
I know when I make an enquiry to review one manufacturers case I was told I could not slate it, so I told them sorry for wasting there time.
No point in reviewing a case if you can't be honest, why I have a deep distrust of the major hardware sites, especially with something which can be highly subjective like a case.
I know for a fact when I got my Xaser III SKULL I thought it was the best case ever, until I tried better.
You can not benchmark a case unfortunately, what you have to do is find someone with similar case choice in the past to you and see how they found the upgrade.
Or if they use a Vento, just recommend them anything else and they will be happy.
