Unmatched Experience

Best Rated Service in the Industry

StealthMachines has held the highest customer satisfaction in the gaming PC industry since 2004. Don't take our word for it.

★★★★★

Absolutely the best custom PC experience I've ever had. The machine arrived perfectly packed, booted first try, and runs flawlessly. Josef personally answered my pre-sale questions within the hour.

I've bought three machines from StealthMachines over the years. The quality is consistent, the communication is excellent, and the warranty coverage is unmatched. I won't go anywhere else.

I needed a Threadripper workstation for 3D rendering. StealthMachines walked me through every component and the machine has been running 24/7 for two years without a single issue.

Because we're small, our focus has always been on treating every customer like our only customer. We don't sell out. We don't compromise on quality. Our customers find us because their friends were treated so well, too.
