wondering what computer i should get?

im not very knowledgeable about computers and stuff but ive been wanting a new one for a while. i was curious if there was anything in particular i should be looking for.

i would like one of those computers that are like, box shaped (desktop computers i think)? ive always called them PCs but i think thats wrong. sorry again lol i know almost nothing about computers. i also have a microsoft acc and i have like everything on there and i would like to keep all that stuff; i assume thats somewhat important?

i usually use my current computer for schoolwork, photoshop/adobe stuff, gaming (js like minecraft, stardew valley, coral island etc nothing super serious).
