Five once-common PC-building habits—choosing a full tower by default, making every component glow, manually overclocking, building a custom liquid-cooling loop, and delidding a CPU—are no longer automatic choices for many builders. That is not the same as saying they have disappeared or are wrong for everyone. The better lesson is to match each choice to your space, components, workload, maintenance appetite, and risk tolerance.
The list is a retrospective framing, not a measured ranking of market trends: there is no sales data here showing that builders have broadly abandoned these practices. Each is still useful in the right build.
1. Full-tower cases as the default
A full tower used to feel like the safe choice: more room to work, more space for components, and easier expansion. Today, a compact mid-tower or mini-ITX case may be a better fit when desk space matters and the build does not need extensive expansion. That is a choice, not proof that compact cases have replaced full towers across the market. The trend list comes from a secondary summary, not market-share data.

What to check before sizing down
- Motherboard format: Confirm the case supports the board you plan to use.
- GPU dimensions: Check card length and thickness against the case’s published limits.
- Cooling clearance: Account for the CPU cooler, radiator, and fan placement you intend to install.
- Airflow and heat: A smaller enclosure can make cooling layout more constrained, especially with heat-intensive components.
- Expansion and build access: Consider additional drives, cards, cable routing, and how much room you want while assembling or upgrading.
A large case remains practical for a highly expandable system or a build with demanding cooling requirements. Choose the smallest case that fits the hardware and cooling plan you actually need—not the smallest case on principle.

2. All-RGB builds as the expected look
RGB lighting has not died; it has stopped being the only obvious way to make a PC look intentional. Tom’s Hardware points to newer cases without RGB while noting that builders who want illuminated components remain. The useful shift is greater choice: a restrained, unlit build can look finished, and a brightly lit one is still a valid personal style.
Lighting is an aesthetic decision, not a performance requirement. Before paying extra or adding more wiring and controls, decide whether the effect matters to you and check that the components’ lighting systems work together as you expect.
3. Manual overclocking as a routine performance upgrade
For many mainstream builds, manually raising CPU clocks takes time and can add heat without delivering a worthwhile improvement in the workload that matters. Modern processors already adjust frequency automatically, and thermal limits can constrain sustained performance. This makes overclocking less compelling as a default step—not useless in every case.

Maximum PC’s April 2024 build guide likewise says its authors do not find overclocking worthwhile in the context they describe. PC Gamer’s Nick Evanson argued in February 2024 that gaming features such as upscaling and frame generation further reduce the incentive to spend time tuning clocks. These are context-specific judgments, not evidence that all workloads or enthusiasts have the same needs.
When tuning still makes sense
- You enjoy benchmarking or experimenting and accept the time required to test stability.
- Your specific workload benefits enough to justify extra heat, power use, and troubleshooting.
- You have a clear performance target and can compare results under consistent conditions.
If your goal is simply to get a new system configured well, check that its automatic boost behavior is functioning as intended and consider enabling a compatible memory profile in firmware. Memory profiles are a separate setup choice from manually overclocking the CPU.
4. Custom water-cooling loops as the obvious high-end upgrade
A custom loop can be visually striking and rewarding to build, and it can suit a particular thermal goal. But it is also a more involved project than installing air cooling or a closed all-in-one liquid cooler. Construction, compatibility, draining, troubleshooting, and later component swaps all deserve consideration before choosing one.
Rank #3
TechRadar’s 2024 discussion notes that hard tubing can require draining and disassembly for service, while soft tubing without quick-disconnects also presents maintenance considerations. It argues that readily available AIOs and fans can make a custom loop harder to justify for ordinary builds. That is a case against treating a loop as the default—not against building one for a deliberate reason.
PCWorld describes custom loops as among the more complex DIY cooling projects, while noting that pre-bent tubing kits and distribution plates have made some parts of the process more accessible. Easier construction does not remove the need to plan maintenance or verify component compatibility.
Decide based on the whole ownership experience
- Choose a custom loop if the build process, appearance, or a specific cooling objective is worth the added complexity to you.
- Prefer air cooling or an AIO if straightforward installation, service, and upgrades matter more than a bespoke loop.
- Plan for future changes: Consider how you will drain and access the system before settling on tubing and component layout.
5. CPU delidding as a casual temperature tweak
Delidding means removing a CPU’s integrated heat spreader (IHS), a physical modification with meaningful risk. Intel’s support guidance for the Intel processors covered by its answer is direct: “No, removing the IHS (known as delidding) is not recommended, and it will void the warranty.” Read Intel’s delidding guidance before considering the procedure.
Intel also says tampering can violate the three-year limited warranty for Intel boxed processors in its warranty guidance. Warranty terms depend on the product and eligibility, so check the terms for the exact processor rather than applying Intel’s policy to every CPU maker or model. Intel’s page on physical damage and external causes explains its boxed-processor warranty context.
For a typical builder seeking lower temperatures, delidding is not a routine first step: it trades a possible thermal objective for physical risk and potential warranty loss. Consider less invasive cooling and airflow changes first.

| Choice | Ask yourself | It may still fit when… |
|---|---|---|
| Full tower | Do I need its footprint, component clearance, or expansion room? | The system is highly expandable or needs a roomy cooling layout. |
| RGB lighting | Do I value the look enough to pay for and configure the lighting? | Illumination is part of the style I want. |
| Manual overclocking | Does my actual workload benefit enough to justify testing and added heat? | I have a specific tuning goal or enjoy the experimentation. |
| Custom loop | Am I comfortable building, servicing, and planning upgrades around it? | The project itself or a particular cooling objective matters to me. |
| Delidding | Is the potential thermal gain worth physical risk and warranty implications? | I am an informed specialist who has checked the applicable manufacturer terms. |
There is no single new rule that replaces these old defaults. The practical change is to treat case size, lighting, tuning, cooling, and CPU modification as distinct decisions rather than badges of a “proper” PC build.
