Quick Answer
All-in-one PCs are niche in SA because they trade upgradeability and gaming performance for a tidy single-unit design — the screen and components are fused, so you cannot swap the GPU or easily add storage. For the same money, a tower PC plus a separate monitor gives far more performance and a clear upgrade path. AIO PCs suit offices and tight spaces, not gamers or builders.
Why builders skip all-in-ones
An all-in-one packs the PC behind the monitor, which looks clean but locks you in: laptop-class parts, limited cooling, soldered or hard-to-reach components, and no room for a proper graphics card. For PC builders who value upgrading the GPU, adding drives, or replacing the CPU on an AM5 socket later, that is a dealbreaker. A standard tower offers all of those options for similar or lower cost.
When an all-in-one makes sense
AIO PCs work for reception desks, small offices, or homes where space and cable tidiness outweigh performance and upgrades. They are not built for gaming — the integrated or mobile GPUs cannot match a desktop card, and you cannot upgrade them. If gaming or future-proofing matters, a tower from around R12,000 with a B650 board, a desktop GPU pushing 60-90 fps at 1080p and a separate monitor is the better SA buy. Reserve all-in-ones for light, fixed-purpose use.
FAQ
Why are all-in-one PCs niche in SA?
They fuse the screen and components, blocking GPU and storage upgrades and using laptop-class parts. Builders and gamers prefer upgradeable towers for the money.
Can you upgrade an all-in-one PC?
Barely. Most have soldered or hard-to-reach parts and no room for a desktop GPU. A tower lets you swap the GPU, add drives and replace the CPU.
Who should buy an all-in-one?
Offices, reception desks and tight spaces where tidiness beats performance. For gaming or future-proofing, a tower plus a monitor is far better value.
Before you buy
For gaming or future upgrades, choose a tower plus a monitor over an all-in-one — same cost, far more performance and a real upgrade path.
