Just choosing a case for new build, can't decide which one to go for tempted by the P80N as it has direct air flow from 140's but the optical drive bay is obscurred and it means you have to pop the door everytime you want to use it. Z70 has great access in that respect and it has hot swap drives my only caution with it is the side cooling through the drive bay, I have read the review on http://www.kitguru.net/tag/pc-z70-case-review/ and they reckon it runs fine on air. Anyone out there got some opinions or even better has bought a Z70 and can share their experience?
