Which is the best computer (my opinion)

Hello, today I talk about of my opinion of the best computers, but for start, which computer do you choose?
If you like a tower form of PC, you choose one tower which his peaces don't costs a lot, the better are the bigger, than the little, because the bigger forms are a lot of peaces to buy and the price are minus than the little towers.
Now if you like a tower, but do you don't know, which is the best for you, because you are working in a specific, thinks.
For example: You are working which programs, for example photoshop, well, do you choose one of there, this computer will had a graphic target of minimum 2 Gigabytes., because the best are for professional, for example 16 Gigabytes, are for people who works with blender, and bigger designs.
If you work in internet a lot of time, and you have a lot of information, to download, you choose a one computer who have a lot of memory and big quantity of information to safe, the normal, are 250 Gigabytes, and another inportant question is if you like to work very quickly, do you choose one computer who have a good memory of RAM, for example 4 Gigabytes.
And are others, for example for people who workd in a office, or studiants, do you choose a one computer who don't have any memory or space in PC, for example 150 Gygabytes, is good for a lot of types of works, and who have a good ram, 2 or 4 Gigabytes of RAM.
