Custom PC Builds in Kalispell, MT

Off-the-shelf is a compromise. A custom build isn’t. RadioActive builds gaming PCs and workstations to spec in Kalispell — the right parts for your games, your work and your budget, assembled clean and dialed in before it ever leaves the shop.

What we build

• Gaming rigs — built around the games you actually play and the frame rates you want
• Creator & workstation PCs — editing, CAD, photography and heavy multitasking
• Business workstations — reliable machines spec’d for the job, not the shelf
• Upgrades — GPU, RAM, storage and cooling added to your existing PC

Built to spec, dialed in

Tell us your budget and what you’re doing with it, and we spec parts to hit your targets — no paying for things you don’t need, no bottlenecks you didn’t see coming. Every build is cable-managed, stress-tested and updated before pickup, so it’s ready to run the moment you get home.

Local support that sticks around

Because we’re a local Kalispell shop, we’re here after the sale — for questions, upgrades or a tune-up down the road. Building a sim setup? Pair a custom rig with our racing & VR simulator installs. Need the old machine fixed instead? That’s our repair bench.
