You can get a hyper 212 evo cooler for $25.
Also, I wouldnt buy a used PSU, you dont know how old it is. Even if its a recent model.
And a Used HDD might have things on it you dont want, and it could be a really old model which could be significantly slower then newer ones from normal use.
what about a h7?
That can be found for $39.
so a hyper 212 is better ?
Well actually the H7 is better then the Evo, but is $10 more expensive.
TBH, you could get either one, up to you.
