What is the major different between an NLX and an LPX form factor?

The major difference between NLX (New Low Profile Extended) and LPX (Low Profile Extended) form factors lies in their motherboard design and expansion capabilities. NLX supports a more modular approach, allowing for easy replacement of the motherboard and components, while LPX typically has a fixed motherboard design with integrated expansion slots. Additionally, NLX cases often offer better airflow and cooling options due to their design, whereas LPX cases may have more limitations in terms of space and component accessibility.
