Extreme PC Build | Most Powerful Computer Core Components

CPU logo Intel Xeon Scalable processors offer a balanced architecture, optimized for many workload types and performance levels, all with the consistent, open, Intel architecture you know and trust, that delivers built-in AI acceleration and advanced security capabilities. Intel Xeon Scalable processors allow you to place your workloads securely where they perform best-from edge to cloud.

Storage logo Every PC we sell comes defaulted with an NVMe M.2 SSD! M.2 SSD Drives and SATA3 Solid-state drives (SSD) have no moving parts, so they make no noise, have fast read times, and are more reliable than standard mechanical hard drives. Standard mechanical hard drives are much less expensive per gigabyte, so use a high capacity drive for storing your large files.

Video logo Quiet Video Cards We choose the quietest video cards available in the market. Every video card choice is either fanless or cooled using a stock hybrid fanless cooler. Hybrid coolers stay with their fans off unless the GPU is really working. This prevents the card from overheating and is still very quiet. Most people never know that the fan has turned on. As well as being absolutely silent every video card offers support for at least two monitors simultaneously, many with options for more.

Motherboard logo Reliable SuperMicro Motherboards This workstation class motherboard features extreme reliability and excellent manufacturer support. Our motherboards use fanless heatsinks and heatpipes to effectively cool the chipset heatsink and voltage regulators, without the use of noisy fans.

Ram logo High Quality Memory This workstation comes with high quality Supermicro certified ECC memory. Each memory module is matched specifically to this motherboard for compatibility.
