Lenovo 4C57A87624 network card Internal Ethernet 100 Mbit/s

Product Overview

AI-generated summary

At £1,034 ex-VAT, this Lenovo-branded 100 Mbit/s internal Ethernet card is hard to justify for most businesses unless you’ve got a very specific compatibility reason. In 2026, paying over a grand for a 100Mbps interface is usually a sign you’re buying “it works in this one legacy box” rather than best value. If you’re trying to improve performance, reliability, or future-proofing, you’ll typically be better served by moving to at least gigabit (especially for anything file-heavy, server-to-storage traffic, or modern cloud/VPN workloads).

That said, there *are* a couple of sensible use cases: if you’re maintaining older Lenovo hardware that only supports particular network modules, or you need a like-for-like replacement to avoid downtime and configuration headaches, buying the official Lenovo part can be worth the premium. Also, if the connected network is already limited to 100Mbps (older switches, segmented legacy environments), the extra cost buys peace of mind more than speed. If you’re buying for anything greenfield or mixed infrastructure, I’d strongly question the spend and push for a better-value card that matches your network’s actual throughput needs.
