Cheap PC Fixes That Punch Above Their Price
Six small things that change more than the components people buy instead. All inexpensive, all unglamorous, all solving a problem you can name.

Six small things that change more than the components bought instead of them. The organising principle: it must cost a small fraction of any component upgrade, solve a problem the owner can name, and demonstrably prevent or fix something rather than marginally improving it.
Nothing here is exciting and none of it will be visible in a photograph of the finished machine, which is the usual reason these get skipped.
A note on this collection: chosen on what each fixes relative to what it costs, not on a set bought and compared here. See how we test.
A precision screwdriver set
A set with the small Phillips and Torx sizes a case, a drive and an M.2 retention screw actually need.

Precision screwdriver set
Buy for the bit range and a spinning end cap. Handle material matters far less.

A screw and standoff kit
A bag of the generic fasteners cases ship exactly enough of, and second-hand cases ship none of.

Rubber grommets for a mechanical drive
Washers and stepped screws that break the path between a spinning drive and a steel chassis.
HDD anti-vibration mounts and grommets
Shouldered screws matter — a standard screw crushes the grommet flat and undoes the point.

A GPU support bracket
An adjustable pillar holding a heavy graphics card level so the slot is not carrying it.
GPU anti-sag support bracket
Set it to hold the card level, not higher, and fit it with the case in its final orientation.

Full reasoning in why heavy graphics cards sag.
An outlet tester
A plug with three lights that says whether a socket is wired and grounded correctly.
Surge protector outlet tester
Rules out the socket, the ground and the extension lead. It says nothing about anything inside the case.

SATA cables with locking latches
Data cables whose connectors clip rather than resting in place.
SATA data cable with locking latch
Right-angle versions help in cases where the cable would otherwise press against a side panel.

What was deliberately left out
Anything electrical and unbranded. PSU cable extensions, SATA power splitters and angled GPU power
adapters are all cheap and all excluded — the failure modes are fire and destroyed hardware, and this
site will not recommend them without hands-on testing and the relevant standards. The reasoning is in
docs/pc-product-list.md.
Thermal paste. Cheap, and rarely the actual problem on a machine that has never been cleaned. It is a maintenance consumable rather than a fix, and it appears in when to replace thermal paste with that caveat.
Anti-static wrist straps. Genuinely useful on carpet in winter and closer to a ritual on a hard floor in summer. Too conditional for a list about things that reliably punch above their price.
RGB anything. Not on price grounds — plenty of it is cheap — but because none of it solves a problem anyone can name, which is the entry requirement here.
