how about AMD Legion ? This alone will weight almost 2.5kg plus the price has included 3 years warranty too.

you need to sign up with a university email account e.g. INTI, Sunway etc

Also no. I have all 3 accounts, normal, student & business accounts
The business accounts just revise the original price to be higher and after you use the discount code, it will be the same as a normal account. Same thing with student account as well

When FRONTLINER & GIVINGUP discount code was still active, they give the biggest discount
Sadly, neither of them is available for use nowadays
