Hi, i've got a generic case one of those of 30bucks... i bought it when i don't really know how important a good case is... i would like to know if i should try on cutting hoes all over it to improve airflow, ovbiously in the adecuated side and with a corrent flow direction... common sense in other words... or just... go for another case, like a Lian Li PC5 for example, i know it's really superior than mine but it's not free and i would pay it a hundred bucks, i woudl like to avoid doing so... but if it is the only option... let's see... please help and advise me, thanks!
