Key strengths
3 M.2 storage positions and 4 SATA connectors provide several drive-connection options.
1 × Realtek 2.5Gb Ethernet provides a wired network connection.
Before you buy
M.2_1 supports PCIe 5.0 x4; M.2_2 and M.2_3 support PCIe 4.0 x4. The listed Intel RAID support is for SATA storage.
Check the exact processor, BIOS and memory kit before purchase. The 256 GB ceiling and listed overclocking profiles are configuration limits, not a tested build guarantee.
The inspected specification does not verify an included wireless module; plan around the wired connection unless the exact retail configuration confirms one.
