  1. Thanks for your article “The Smallest ATX Case: Best SLIM and Compact ATX Cases Reviewed”. I’ve been looking for a case with a length of 16 inches or less (front to back) that would hold a full size ATX motherboard. The RIOTORO CR1080 is exactly what I’ve been looking for. They have a new version of it, the RIOTORO CR1088, that has some nice improvements including RGB lighting. I am planning to buy that version on Amazon. Here is the link: https://www.amazon.com/RIOTORO-CR1088-Prism-Lighting-Window

    Thanks again!

  2. Thank you for the article. I currently have the HAF featured here. I was googling, because I found it took big. I’m moving it around much, so I love the handles on it, but it’s too big. I’m running a 1080 (non-ti), two ssd’s and a single hdd in it. And I think apart from the psu, everything could’ve fit on the upper deck, so there ought to be a case that’s just above half as big. You don’t happen to know about any do you?
    (might end up designing my own)
