If you decide to use your PC as a physical server, you generally won’t have to pay any subscriptions. It’s free. However, there are some important factors to consider.

1. Operating Costs: While there may not be specific subscriptions, you need to be aware of the operating costs. Running a physical server can consume a significant amount of electricity, which will reflect in your utility bills. Additionally, you might need to invest in cooling solutions to keep your server hardware from overheating.

2. Hardware Investment: Setting up a server requires appropriate hardware components, such as a reliable CPU, RAM, storage devices (HDD/SSD), and possibly redundant power supplies. There might be an initial investment to ensure your PC can handle the server workload.

3. Software Costs: Depending on the operating system and applications you intend to use on your server, software costs might be associated with licenses or commercial software. However, there are many open-source solutions available that you can use without additional fees.

4 Network Infrastructure: For a server to be accessible from the internet, you need a stable and fast internet connection. This might require a higher-tier internet plan, which could increase monthly costs.

5. Maintenance and Upgrades: Over time, your server may require maintenance or upgrades, such as replacing faulty components or increasing storage capacity. These expenses should be taken into account.

In summary, while there might not be direct subscription fees for using your PC as a physical server, there are still costs associated with hardware, software, electricity, and internet usage. It’s essential to carefully plan and budget for these expenses before running your own physical server. Alternatively, you could consider using a cloud-based solution, which may offer more flexibility and potentially lower costs depending on your needs.
