What Was Your First Case MOD?

[Uranium-235]

a dinky little fan

In 1983 I wired a real ASCII keyboard to my Timex Sinclair, replacing the vinyl keypad. The following year I wired a Radio Shack push button as a reset switch on my Commodore SX-64.

I graduated to modding PCs only recently. Last month I cut four holes in a steel case for side-intake/top-blowhole fans.

I cut two 8mm holes for fans that i installed on top and side than a window

now water kewling

should blowholes up top blow air out of the case or suck in?

assuming that side panel blow holes are sucking air into the case
and on the back you have fans blowing out of the case

Generally speaking case design has cool air enter from front and bottom to exit top and rear. This is the path that add-on fans should enhance.

I've seen some cases with airflow paths that are not front-to-back or top-to-bottom, but this is the path that most case manufacturers design.
