I took the original "Gaming on the CHEAP" ( https://pcpartpicker.com/b/KTWD4D) and decided to upgrade and mod the case. I upgraded the CPU, motherboard, and CPU cooler. Installed fans, wife adapter and an ssd. Sold the original CPU, mobo and Ram. Wanted more performance and the 2600 was on eBay for $75 and i had to pull the trigger. Found some cheap ram and a small ssd to improve start-up times.
I wanted better airflow for the 2600. With the original stock cooler it would idle at 65 C, i then changed the cooler and dropped to 50C and then i modded the front panel and added fans to get the idle down to 37C. I cut out the entire front and replaced it with a metal grate i bought from lowes. In order to fit the fans i had to cut out the DVD/CD drive cage. And after i I cut out the front, the front I/O was also removed so i drilled a whole on the top and wired up a switch i made. Also put in an RGB strip in the front in hopes i can sell it faster.
Overall fun build. Modding was fun and helped performance overall so can't say i regret it.
