I think your right.. i should remove cd drive...
Tbh, i love to get the K series, but they don't come with stock fan and my budget is limited so i opted to buy non-k series..
My friend told me i can OC non-k but i don't know if its true.
I'm considering that... Faster loading / boot time
I opted z170 chipset for upgradability..
which psu should i choose.. any suggestion ?
