Circular IT ecosystem integrator.
Core 4 Solutions operates at the center of a unified, three-part hardware ecosystem engineered to eliminate procurement friction at every stage.
Powered by Rhino, our supply-side purchasing engine with over 20 years of wholesale sourcing and broker relationships, we gain first-look access to high-demand inventory.
As the end-user facing partner, Core 4 configures and delivers custom server, storage, and networking solutions tailored for cloud providers and growing enterprises.
For organizations that need dedicated compute rather than hardware, Charg builds and operates GPU clusters under contract, handling deployment and day-to-day technical operations.

Industry pioneers meeting the moment.
Just three years after Cory Larsen & Mike Mattson founded Rhino Technology Group, a Minneapolis brokerage hub, they saw an opportunity. Whiplashed by eBay’s ever-changing rules, they founded Core 4 Solutions to better meet the needs of end users: combining high-touch consultative guidance with direct access to an extensive supply-chain inventory.
From that point on it’s been a history of strategic, aggressive expansion, growing from an initial 900 sq ft warehouse with 3 employees to over 65 employees and a 42,000 sq ft technical facility. More than ever, we’re giving cloud providers and growing enterprises a smarter, faster way to build, maintain, and scale their hardware infrastructure.
Completing your IT lifecycle with disposition.
Whether you’re planning a complete hardware refresh or simply need to dispose of old equipment, we also take care of IT hardware disposition. At Core 4, we prolong the lifespan of valuable materials by recycling as much electronic waste as possible, while providing a way to offset the costs of your IT investment.
