Questions

Why not just buy a prebuilt PC?

Prebuilts often save money on the parts you don't see: power supply, motherboard and cooling. We pick every part for your use and tune it.

Can I bring my own parts?

Yes. We'll build with them, check everything works together and tell you honestly if a part is holding the system back.

Do you upgrade existing PCs?

Yes: graphics cards, storage, memory, cooling, and full rebuilds into a new case.

Is the build tested?

Every PC is stress-tested and checked for temperatures and stability before it is handed over.
