Here I leave my first mod. everything began to improve the refrigeration and in the end I ended up giving a different touch to the case.

-I installed heatsinks to aliexpress ram memories in white color.
-I made a custom backplate gpu with acrylic.
-I made a cover of the power supply with acrylic.
-Paint the original white psu cover.
-I made holes in the side of the front to have better air intake
-I put some fangrill.
-I made a small cover for air cooling.
-I put vinyl on the side of the gpu.
-I put a vinyl on top of the SSD.
-I added a full acrylic window.
-I added a 5v white led strip at the top, stuck with some magnets to move it if I want.
-To finish buy some extensions of sleeving and send print a cable combs in 3d

It is a very simple and economical mod. Buy most parts in second-hand stores and aliexpress. Apart from that, I just need a little paint, acrylic, imagination and some vinyl.
