DIY Modem?
Yes, it's feasible to construct your own router. Regarding modems, some are available as PCI cards for installation.
Which connection do you need? DSL, fiber, cable, or something else? You haven’t mentioned your preference.
Ensure the designated router runs the required operating system on your device
For a cable modem, offering DOCSIS 3.0 or 3.1 PCIe cards isn't viable, so you're safe in that regard.
I was discussing cable too, but I should have said that earlier. Personally, I don’t require anything like this. It was just something I wanted to know. However, it might be useful for those with very basic setups—like someone needing only one PC connected to the internet, where a PCIe modem could eliminate the need for another device. Or perhaps for someone who simply wants to create their network without any specific goals in mind.
I haven't seen any cards specifically designed for the consumer market. The options mainly range from ready-made DOCSIS modems to costly data center equipment, with no middle ground.
I believe 'building your own modem' differs from 'are there any PCIE cable modems.' I expected you'd focus on merging Docosis and Ethernet standards at the physical layer. Some enterprise router modules support cables, but the latest ones are quite costly. A dedicated unit seems more practical—you won’t have to wait for synchronization once your PC starts, and external units would consume similar power to an internal card. In short, you’d be sacrificing features by using an internal card, which adds extra cost without extra benefits.
