Any Dell or Toshiba in that price range would be more than suitable. I cannot advise on Mac's as I haven't used one in 20 years. As I do a lot of graphics as well as run some very large mrp systems, I decided on a gaming computer (alienware now produced by Dell), it is large and heavy and I wouldn't advise it if you have to move around from class to class, it is super fast and reliable and it has a full keyboard with num pad)
I would never buy another Acer, Fujitsu or HP again. I find them unreliable, operating software often runs slow on them and customer service is most unhelpful. Acer and Fujitsu have issues with display and keyboards. HP has lots of issues with motherboards.
If you are taking notes for school, have you thought of a tablet? My oldest son goes to university and many of the students take notes on the tablet (engineering so lots of sketches).
I use Microsoft One Note for many of the projects I do at work, it was originally designed for students.
