I have an existing SFFPC build. I would like to upgrade the case to a larger one for better cooling. The current case (LIAN LI A4-H2O) becomes untouchably hot within 10 minutes when I play games (with GPU set to 75% power level, GPU temps are usually under 80 deg). CPU temperatures quickly reach 100 deg and trigger throttling when I do video encoding. I built this PC when I was in a foreign country, and chose this small case for carrying in plane. Now, I am using it in Kerala where room temperature is in the 34-40 deg range with no a/c.

Please suggest a good case (budget: upto Rs. 9000) and a good AIO that would help me in keeping things cooler.
