side note: I've seen these small circular displays inside the pc with giffs or repeating animations. Is that to do with the cooler? Could I just buy one and attach it on?

You can get a 5% student discount on refract builds. I see two front intake fans, one exhaust fan at the back and one CPU cooler.

You're saying thats good then?

Custom PC builds rule!

With a combination of new and used items. With the highest quality power supplies (Seasonic with 12 years warranty). Sensible component choice (EG 12th or 13th gen Intel i3 CPU, 16 GB DDR5 RAM, ATX sized motherboard).

Buying a used case off ebay for £1 to £5 will save you a chunk of money and make your PC less desirable to burglars.

It's so so easy to buy a PC with a crappy power supply that fails in 2 years time. With an overspecced CPU that makes no difference to your game speed and fps. And too much RAM that makes no difference to anything apart from your bank balance. And too much hard drive space, when you'd have been better off with a faster SSD and adding more SSD's as and when the need arises.

Use this as a reference for comparing GPU's:

Also, aim for a big 4k monitor (look at new and used deals). And an ergonomic gaming mouse (wired is fine) and a mechanical keyboard and a big mouse mat.

Assembling the PC yourself is easy. It all just screws and plugs together.

Some people simply do not want to self-build. That is what I and many gamers do, it is not for everyone.
