Welcome to The Forums!
But yeah, this should be in Cooling.
And you need to update the ghetto quotient, man!
Folks in here regularly do caseless systems, carboard boxes, zip-tied fans, box fans instead of the side panel and more, lol.
And I haven't even brought UP some of the case mods that look they were done by merely ripping apart the metal with brute strength instead of a cutting tool!
If you want to go for Ghetto Gold around here, you have to do some pretty ugly, cheap and cheasy stuff to catch up with teh rest of us....
But you are started on your way!
You'll get the hang of where to post stuff before long, but the general idea is to keep things in the most appropriate area for the thread- since this is about Ghetto Cooling, the Cooling Section is the best fit.
If you were to post about using pliers to rip an airflow hole in a side panel (done it
) then it would go in Alternative Modding, and so on.
