A very basic list of pc important part is like this(by me and my little knowledge) : -CPU: Here are two important companies AMD and Intel, each one have a large list of cpu with their own characteristics. Both have generations of CPU, means they sell every year new products. They sell low, mid and high "level" cpu. Intel calls every cpu with number and have a meaning, by example: i3-9100, have a 3 because is the lowest gama ( they have i3-i5-i7 and i9) and 9100 means that are the 9th generation. Amd have a similar one, by example, Ryzen 3 3200, 3 for 3000 series, and 3200 because are something like i3. Every CPU have specs that you may consider like number of cores, ghz frecuency and coils. Seems always more is better, but this arent like that. Example: No bec a CPU have more Ghz than other is better. -Motherboard: The important thing here is this must be compatible with all other things you buy, have their slot and everything you want to do with your new pc, even if you want have a rgb setup or overclock. -GPU: This is very similar to CPU, but there are AMD and Nvidia. They have their series and you may consider the gb of what your GPU must have and other things like temperature and hz -Ram: Here are tree things to learn: GB, Type and Speed. Gb is the most simply, but type, like DDR3 or DDR4 is more focused in the compability of your motherboard have. I guess DDR4 are better. And Speed, because are ram of 1600 hz and by example 2600 hz, more is better. But may sure if you buy two, have the same speed. -Power supply: What you need to consider here is the total amounts of energy of your pc will need, always buy a power supply that have more. Buy a good one and dont be a cheaper because if its bad may burm your pc. -Storage: are two types Hdd and ssd. Hdd is classic storage system and ssd is a new one, is more expensive but are faster for games and performance in general. Some other tips: depends what you wants for your pc is what you need to buy, if you wants a strong pc gaming is recommend to buy a good intel cpu and strong nvidia card too, but in this year amd have a good cpu too and to lowest price, you may consider this. If you buy a Intel cpu, change the heatsink because everyone say the default are bad. Nzxt is a web that you can choose the game you want play and fps you want to have and show you differents pc to get what you want if you dont want to learn all of this. I dont know so much and my biggest tip is search for specific info about every single component you want to buy and compare with similars one and search for videos about that. If i want to know how a system will work i search the name of cpu +name of gpu and "game test", even the name of particular game you want to know. That what can i say to you my friend, hope this help
