Hand-Built in Carlisle

Custom PC Builds

Every machine we build is engineered to order — spec'd, assembled, and thoroughly tested in-store before it leaves our hands.

Why Choose a Custom Build

Built for You. Not Off the Shelf.

Mass-produced PCs are built to a price point. Our custom builds are built to a purpose. Whether you're after maximum gaming performance, a silent workstation for creative work, or a reliable home office machine, we spec the right components for what you actually need.

We source quality parts, assemble everything in-store, run full burn-in testing, and deliver a machine that's properly set up and ready to use from day one. No bloatware, no compromises.

The Process

How a Custom Build Works

Simple, transparent, and no surprises.

01

Tell Us What You Need

Give us a call or drop in. Tell us what you'll be using the machine for — gaming, work, streaming, content creation — and we'll build a spec around your requirements.

02

We Spec the Build

We put together a component list and talk you through the choices. No jargon — we'll explain what each part does and why we've recommended it.

03

Parts Sourced and Assembled

We order from trusted UK suppliers and assemble everything in our Carlisle workshop. Every cable managed, every component seated correctly.

04

Tested and Handed Over

Full stress testing under load, Windows installed, drivers updated, and everything configured before you collect. We walk you through the system on pickup.

Component Upgrades

Already have a PC but need more power? We upgrade existing desktops and laptops to breathe new life into older systems.

Sometimes you don't need a whole new machine — just the right upgrade at the right time. A new SSD can transform a sluggish laptop into something that feels brand new. More RAM, a better GPU, or an updated CPU can extend the life of a desktop by years. We advise honestly on what's worth upgrading and what isn't.

Desktop Upgrades

  • Graphics card upgrades for gaming and creative work
  • RAM upgrades for faster multitasking
  • SSD installation (replace HDD or add alongside)
  • CPU upgrades (same-socket motherboard permitting)
  • Cooling improvements — new heatsink or AIO
  • Power supply upgrades for higher-end builds

Laptop Upgrades

  • SSD upgrades — dramatically faster boot and load times
  • RAM upgrades (where not soldered)
  • Battery replacement for better portable life
  • Compatibility assessment before purchase
  • Full data migration from old drive to new
  • Operating system reinstall if required
