The second chassis I ever bought to build a rig in was the Antec 900 in its original configuration. Slowly as time went on, I found the need to paint the interior, as primed steel in my opinion is ugly to look at, especially in cases with windows. I had this chassis for quite some time, and the mods kept coming. They included a PSU hole in the bottom so I could flip my PSU, and eventually water cooling and the required mounting and routing of the tubes; these both required removal of all the components to make the mods happen. The chassis was cool inside, but from what I remember it sounded similar to a jet engine at take off; something I have tried to deviate from in my normal everyday use.
