Looking for Best Practices to Organize Hardware Setup

Hello everyone,
I’m currently working on improving a small office IT setup that supports both daily operations and light server workloads. Performance is fine, but the physical layout inside the racks and cabinets could be better, especially when it comes to airflow, accessibility, and future maintenance.

While reviewing different approaches, I came across server cable management practices used in enterprise environments and started wondering how much of that can be practically applied in small-to-mid business setups. Clean routing, labeled connections, and proper spacing seem important, but space and budget are always limited.

My goal is to make the setup easier to maintain, reduce downtime during upgrades, and keep everything well-organized for audits or troubleshooting. For those managing business IT infrastructure, what simple steps have worked best for you? Do you plan cable layout before hardware installation or improve it over time?

Appreciate any insights or real-world experience you can share.
