It depends on what you want to do with your PC. For school, work and daily use. The processor, storage, memory and display would need to be basic. For gaming, coding, programming, music and video editing. You would need a newer processor, use an SSD instead of HDD. You would need at least 16 gb of ram for memory and have at least 50 cm for display.
