AI-generated summary
For £626.53 ex-VAT, this Lenovo “internal Ethernet” card is only a good buy if you’ve got a very specific reason to go internal with Lenovo-brand hardware—typically in a Lenovo server environment where you want known-good compatibility, clean firmware support, and minimal faffing about with drivers and teaming. In that scenario, it’s the kind of no-drama upgrade that keeps your network stable and supportable, which matters more than squeezing out a few pennies versus generic options.
I’d be cautious (or skip it) if you’re buying for a general PC/workstation or a mixed vendor setup. At this price point, you should sanity-check whether you actually need the performance class and whether your switch ports, cabling, and chassis expansion options will support it properly—otherwise you’ll pay “server tax” without getting much real-world benefit. If your goal is simply reliable 1G/10G connectivity for everyday workloads, this is likely overkill and you’ll get better value from a more cost-effective NIC unless you specifically need Lenovo’s ecosystem fit.
