Overview

This server is built on the ASUS RS521A-E12-RS12U, a single-socket 2U rack server with 24 memory slots and twelve 3.5-inch front bays. It suits a single GPU next to storage-heavy work, and the chassis has room for up to two double-slot cards.

You choose the GPU, processor, memory and storage, and see an indicative price in rand as you go. ASUS's compatibility list doesn't name the GPUs in our configurator for this series, so we confirm your card on your quote. We help you source and deploy the system.
