Common Questions

Frequently Asked Questions

How much does a custom PC build cost?

We work to your budget and recommend the best components for your needs. Contact us for a quote based on your specific requirements.

Do you supply all the components?

Yes. We source all components from reputable suppliers — ensuring genuine parts with full manufacturer warranties. We can also build with components you've already purchased.

How long does a custom build take?

Custom builds typically take 3–5 working days from component delivery. We build, configure, install Windows and drivers, stress-test, and deliver a ready-to-use system.

Why Choose Our Custom PC Build?

Building your own PC should be exciting, not stressful. At 19 Computing, we design and assemble custom PCs tailored to your exact needs and budget — whether that's a gaming rig, a video editing workstation, or a reliable office machine. We select compatible components, assemble everything with professional cable management, and stress-test the complete system before delivery.

Every build includes Windows installation, driver setup, BIOS optimisation, and a full benchmark suite so you can see exactly how your system performs. We also provide ongoing support — if something isn't right, bring it back and we'll sort it.
