ClearOS on a Laptop
ClearOS is typically run on a server or dedicated hardware like a ClearBOX. However, you can also run it on a standard laptop.
If you don't have a CD/DVD drive, see ClearOS USB installer.
Laptops are not designed for years of 24/7 operation so they can overheat.
Only one RJ-45 network interface (Use this one to connect to your modem)
ClearOS may have trouble detecting some of your devices, especially if the laptop is quite recent
Unless you use ClearOS only as a server (and not as a gateway), you will likely need a second (or even third) network interface. Since laptops typically have only one NIC, you should purchase a USB-NIC. See USB Network Cards.
If you are installing at home, you should configure your router to make the ClearOS instance be in the “DMZ”. Of even better, transform your ClearOS instance into a wireless access point
