Could you critique my first PC build for music production and creative work?

Moving to a smaller case later makes sense if portability is important, but check the dimensions of the graphics card, power supply, and 360mm radiator before choosing the future case. Some compact micro-ATX cases won’t fit a large radiator or full-size PSU comfortably. Since you’re considering options such as the CH160 or A3, confirm their exact support for your GPU and cooling layout rather than assuming every part will transfer over.

Since gaming isn’t your priority, the 16GB graphics card may be adequate, but the rest of the parts should still match your creative-work needs. The Hyte case is a relatively expensive choice, and the power supply and cooling options may not offer the best value compared with alternatives from more established lines. Compare the total cost against a simpler airflow-focused case and a good air cooler before committing. Also verify that the motherboard, processor, cooler mounting hardware, and future micro-ATX case all support the same socket and radiator clearance.

For this workload, the build looks heavily weighted toward the case, motherboard, CPU, and cooling while only using one 16GB memory stick. Music production and After Effects can benefit from more memory, and a single stick also runs in single-channel mode, so 2x16GB would be a much better starting point. Consider whether the expensive case and 360mm liquid cooler are actually necessary, then put some of that budget toward 32GB or 64GB of RAM and a stronger overall balance.
