Op.
There is no best chassis. At all. Every person has individual tastes, like not liking RGB or wanting green fans or orange stripes. Every setup is different, like some use liquid cooling with triple fan radiators, some use giant heatsinks, some couldn't be bothered with OC and just use stock coolers. Every situation is different, some want the htpc, some need certain size cases, some want floor placed, some want desk placed.
So there's no case that can fit every criteria for everybody. Cases are very personal, you have to look at it every day, we don't. So you need to get online, search Amazon, newegg, pcpartpicker.com etc and find half a dozen cases you really like the looks of. Then see if they fit your criteria build, needs, wants. You'll end up with 2-3 that are tied and rgsys when you ask opinions as some are better quality, some have better airflow, some have fitment issues you may not know about.
