PC Repairs, Upgrades & Same-Day Builds in Sydney

G-One Computers isn't just a store — it's a working PC workshop in Camperdown, Sydney, open 7 days. Here's what we can do for you and your machine.

Same-day PC building & testing

Order a build (prebuilt or custom) and, where parts are in stock and the day allows, we'll assemble, cable-manage and stress-test it the same day. Every build gets thermal and stability testing before handover — you receive a machine that's been proven, not just powered on. Urgent? Call ahead on 0468 711 728 and we'll tell you honestly what's possible today.

PC repairs

Sydney PC repairs without the runaround: diagnostics, part replacement, thermal service (repaste and fan replacement), storage upgrades and data migration, and fixing the “it worked yesterday” mysteries. We quote before we work — no surprise invoices. Walk-ins welcome 7 days: Mon–Sat 11:30am–8:30pm, Sun 1pm–7pm.

Upgrades

GPU, CPU, RAM, storage and cooling upgrades — including compatibility checking, so you don't buy a part your power supply or motherboard can't handle. Bring your PC in and we'll tell you what's worth upgrading and what isn't. Parts are price-matched, so upgrading locally costs what it would online, plus it's installed and tested by us.

Warranty service — 3-year RTA

Every G-One build carries a 3-year return-to-base warranty. If a covered part fails and we have stock, we swap it on the spot rather than making you wait weeks for manufacturer processing. That's the practical difference between buying from a local workshop and a shipping warehouse.
