Re: do'es my case have adequate ventilation for a 3rd HDD?
If you want more than 3 internal you'll have to get creative with mounting, I'd grab a cheapy case from Newegg that can fit more drives. You can add as many drives as you have SATA ports for, just keep in mind that PSU may need an upgrade at some point.
