Description from Seller

Looking to upgrade my AM4 gaming PC to AM5 gaming PC. Not looking to part out.

I have upgraded the CPU and RAM.

Thermaltake Reactor 380 Liquid-Cooled PC (AMD Ryzen 7 5800X3D, RTX 3080, 32GB 3600Mhz DDR4 RGB G.Skill, Seagate FireCuda 520 NVMe 1TB, WiFi, Win 10 Home) Gaming Desktop Computer TW1B-B550-R38-LCS

What better way to power your battle station than the Reactor 380. With a list of impressive specs and a small footprint, the Reactor is sure to fuel games sessions where ever you find yourself. A Ryzen 7 5800X3D matched to a B550 and supplemented with 32gb of 3600Mhz memory and 1TB of Gen4 NVMe storage means less waiting and more games time. Powered by NVIDIA Ampere architecture, experience Ray Tracing and DLSS with the NVIDIA® GeForce RTX™ 3080. Sporting a host of new features and the all new Ampere architecture built with enhanced RT Cores and Tensor Cores, new streaming multiprocessors, and superfast G6X memory for an amazing gaming experience. Assembled in the new Thermaltake Tower 100, the Reactor 380 puts all of its power out on display. Utilizing a combination of tempered glass and mesh panels the Reactor is able to give the best of both worlds for airflow and presentation. All while providing a small footprint to allow for flexibility of desk space.
