Some once-standard PC-building habits are now choices rather than defaults: oversized cases, lighting on every component, manual CPU overclocking, elaborate custom loops, and delidding. That does not mean these approaches have vanished or are wrong for everyone. It means builders have more alternatives, and the practical payoff depends on the build.
1. Treating a full-tower case as the default
A full tower can still make sense for a large, expandable system, but it is no longer the automatic answer for every build. Compact mid-tower and mini-ITX cases can save desk space; the trade-off is that component fit and cooling become more important.

Before choosing a smaller case, check the motherboard format, graphics-card length, CPU-cooler height, radiator support, airflow, and space for future expansion. A roomy case can simplify assembly and accommodate demanding hardware, while a compact case rewards careful planning. The trend list comes from a secondary summary, not market-share data, so it does not establish that smaller cases have replaced full towers across the market. News Minimalist’s summary

RGB lighting has not disappeared, and it is not inherently outdated. The shift is that an all-lit build is one aesthetic among several, rather than an assumed finishing touch. Tom’s Hardware notes both newer case options without RGB and continuing interest in RGB components. Tom’s Hardware’s discussion of RGB styling

Choose lighting for the look you want. If you prefer a quieter, less illuminated system, skipping RGB can simplify the build and its wiring; if you enjoy the effect, there is no performance-based reason to avoid it.
3. Manually overclocking every processor
For many ordinary builds, manual CPU overclocking is less compelling than it once was. Modern processors adjust their frequencies automatically, and thermal and power limits can leave little practical headroom for a manual tune. TechRadar’s Zak Storey describes automatic boost features as having “almost eliminat[ed] the overclocking hobby for most amateurs”—an editorial assessment, not a universal rule. TechRadar’s discussion of custom cooling and tuning
Maximum PC’s April 2024 build guide says its authors do not find overclocking worthwhile in the context they describe, while separating that from enabling memory profiles as a useful setup step. Maximum PC’s PC build guide PC Gamer’s Nick Evanson made a related argument in February 2024: upscaling and frame generation can reduce the incentive to spend time chasing extra gaming performance through overclocking. That is the author’s view, not a finding that applies to every game or workload. PC Gamer’s opinion on overclocking and gaming features
Manual tuning still has a place in benchmarking, experimentation, and workloads where a measured performance gain matters. For a general-purpose or gaming PC, weigh the likely benefit against stability testing, added heat, and time. A memory profile is a separate setting from manually overclocking the CPU.

4. Building a custom liquid-cooling loop just because it looks impressive
A custom loop can deliver a distinctive build and suit a specific thermal goal, but it brings service work along with the visual appeal. TechRadar notes that component changes and troubleshooting can be harder; hard tubing may require draining and disassembly, while soft tubing also needs service planning if quick-disconnects are not used. TechRadar’s account of custom-loop trade-offs
For many everyday systems, an air cooler or closed all-in-one cooler may achieve the builder’s cooling goal with less installation and maintenance effort. PCWorld notes that custom loops remain among the more complex DIY projects, although pre-bent tubing kits and distribution plates have made parts of the process more accessible. They do not remove compatibility checks or ongoing service needs. PCWorld’s overview of recent PC-cooling developments
Consider a custom loop when the process itself is part of the appeal or when your particular build has a clear cooling objective. For ordinary builds, compare workload and heat, noise goals, installation effort, maintenance, upgrade access, cost, and aesthetics before committing.
5. Delidding a CPU for a cooler-running PC
Delidding means removing a processor’s integrated heat spreader, a physical modification with meaningful risk. Intel’s guidance for the Intel processors it covers is explicit: “No, removing the IHS (known as delidding) is not recommended, and it will void the warranty.” Intel’s guidance on removing an integrated heat spreader
Intel also says tampering can violate the three-year limited warranty for Intel boxed processors; warranty terms depend on the product and eligibility, so consult the applicable terms rather than assuming a single rule covers every CPU. Intel’s information about physical damage and processor warranty coverage Delidding is therefore a specialist modification, not a routine cooling step for a typical build.
How to decide what belongs in your build
- Case: prioritize component compatibility, airflow, and expansion needs, then decide how much space you want the system to occupy.
- Lighting: treat RGB as a personal style choice, not a requirement.
- Tuning: pursue manual overclocking when its likely workload-specific gain justifies the testing and heat.
- Cooling: match the method to your workload and noise goals while accounting for installation, servicing, and future upgrades.
- Delidding: consider the physical risk and the processor maker’s warranty terms before any modification.
There is no evidence in the cited coverage that quantifies how widely these practices have declined. The useful conclusion is narrower: none is a universal default, and each should earn its place in a build on fit, function, or personal preference.
