PC Builds

Same instinct as the garage, smaller fasteners. How I plan a build, how the cables get tidy, and the desk gear that holds it all up.

Building a computer and wiring a truck are closer than they look. Both are a power budget, a set of connectors that only go in one way, and a cable run that decides whether the thing is pleasant to live with. I build my own machines, the same way I did the twelve-volt work on the 4Runner, and this section is what I have to say about it that is useful to somebody else. It starts with the two machines I actually assembled in May 2026 — mine and one for a friend, near-identical builds separated by a single line on the parts list — with the real parts, what I paid, my own photographs, and the first-boot screen where I had left the memory profile switched off. The rest is the reasoning that transfers regardless of which generation of parts you are shopping: how to split a budget so the money lands where the performance is, how to make cable management a build step rather than a regret, and what actually matters in the desk hardware everything sits on.

Before you buy

Allocation beats part-picking

The most common way to waste money on a build is not buying the wrong part, it is buying a set of parts that are not balanced against each other. A top-tier graphics card fed by a budget power supply, or a fast processor paired with a cooler that cannot keep it out of thermal throttling, spends money on capability that never reaches the screen.

Decide what the machine is for first, then split the budget by that answer rather than by enthusiasm. A gaming machine puts the largest single share into the graphics card, because in almost every game that is the part deciding the frame rate. A machine for compiling, rendering or video work moves that share to the processor and to memory capacity. A machine that mostly sits on a desk being used should spend proportionally more on storage and quiet.

Two parts are chronically under-budgeted and both are the kind you keep across builds: the power supply and the case. Neither makes a benchmark faster. Both decide whether the machine is stable, quiet, and pleasant to work inside two years from now, and both routinely outlive the parts they were bought for.

The power supply is where the specification is real

Power supply listings are unusually honest by component standards, because the meaningful claims are certified by somebody else. The 80 PLUS program tests efficiency at defined load points and publishes tiers — Bronze, Gold, Platinum and up — so a Gold badge means a lab measured the unit, not that the marketing department liked the word.

Wattage should be chosen from the actual draw of the parts plus headroom, not from the largest number affordable. A supply loaded near its limit runs hotter, runs its fan harder and has nothing left when a graphics card spikes. Headroom is also efficiency: most units are at their most efficient somewhere around half load.

The connector standards are the part that catches people out. Modern platforms have moved to ATX 3.x and PCIe 5.x with a native 12V-2x6 connector for high-draw graphics cards. If you buy an older supply and adapt it, you have introduced a junction that is carrying a great deal of current — and adapters are exactly where high-current connections fail.

Cable management is airflow and serviceability, not decoration

A tidy build looks better through a glass side panel and that is genuinely part of why people do it. It is not the reason it matters. Cables bundled out of the way stop obstructing the path air takes from the intake fans to the exhaust, and a case that moves air is a case where every component runs cooler and every fan runs slower and quieter to achieve it.

The bigger payoff is the second time you open the machine. A build with routed, secured, labeled cable runs takes ten minutes to add a drive to. The same build with everything crammed behind the motherboard tray takes an hour and usually ends with something unplugged that you did not notice until it would not boot.

The technique is the same as automotive wiring, which is why this section exists on this site at all: run before you connect, bundle at the natural bends, secure to a fixed point rather than to another cable, and leave slack where a part will move. Reusable hook-and-loop straps rather than zip ties, for the simple reason that you will be back in there.
