In my region the h510i costs $165 (SGD) and the case that I am now eyeing has become the Corsair iCue 465x which goes for SGD$189, which i may go for, given that I'm paying $24 for 1 extra fan, with RGB and better fans and case airflow design overall. (given how gamersnexus tested this to be ~8 degrees C lower than h510 elite). The 220T retails for $143 here, but I might just be willing to pay extra for a bit more space (given that I will probably put more than 2 3.5" drives than is supported/may put in some 2.5" drives as well, I would like the extra space).
Do you think I need to purchase an additional fan for the back for exhaust though? It is a 3 intake only fan configuration...
