Logisys uses a clear fan chassis with a concave bolt-on adapter that contains a center cold cathode and another that runs around the outside. If you use this setup, you will want to ensure that you have plenty of clearance since the whole apparatus is 41.27mm thick (about 1 and 5/8th inch). That's pretty thick and may not fit between the drive cage and front bezel on some cases. The nice thing about it being removable is that you can switch the lights around so that you can use it as an intake or exhaust fan while keeping the lights shining towards the inside of the case. Hell, if you wanted you could even switch it to another fan with better specs.
