10Gb to 40Gb network cards available for $25 to $50, excluding delivery costs.
The main focus is on the fact that older HP server models with 10Gb/40Gb NICs are being sold cheaply on eBay. The reason behind this low price is their exclusive use of a proprietary connector called FlexibleLOM, which only fits HP Server boards. Although it sounds like a unique feature, it's actually just a rebranded PCIe technology with different pin arrangements. Many of these cards have been refurbished. On the project page, they list supported models such as 561FLR-T and various Broadcom connectors. Some users reported issues with short circuits when installing certain cards, but adjustments like adding small tabs helped. It's recommended to secure the card properly in the case to avoid problems. The adapter project includes PCB files and driver downloads for Windows and Linux. The creator is Toble Miner, and more details can be found on their Twitter profile.
The FlexibleLOM section refers to the actual card model available on eBay, likely all HP cards. It seems the connector type is 'standard' or similar, meaning any compatible card should work. I'm not an expert, but I'm open to guidance from someone more experienced.
I consulted my friend regarding the shorting problem. The card was quite tall, and it wasn't secured properly when installed, so inserting a cable into the PCIe slot caused the card to shift, resulting in a short. Adding tabs with screws provided enough stability to prevent movement.
