Custom builds · quoted
Specified to the monitor and the workload you actually have.
An expensive motherboard does not automatically make a faster gaming PC. Budget goes to GPU, CPU, cooling and memory according to resolution, refresh rate and use.
Air, done properly
Sufficient for the vast majority of systems. Fan placement and pressure balance matter more than lighting. Cooler selection should match actual TDP and case constraints.
Soft-tube loops only
Quoted separately. Justified when noise, multi-hour loads or specific thermal targets require them — not because they look impressive. I will not build a loop that is difficult to maintain later.
