Now this computer is gonna run me a little over 3k$ and i was wondering iff the five 80mm fans that come with the case,CoolerMaster Liquid CPU Cooling Fan ,and a 680watt power supply will be enough to cool and power my computer without overheating with extended hours(12+)of play.the specs are as following

ALUMINUM X-Navigator Server 420W W/ Window & Temp Dis,Fan Control

It's all about air flow. Have more fans blowing air out than sucking in, creating negative pressure. Have the out fans at the top of the case, in fans at the bottom and preferably on opposite side to each other to create a flow of air diagonally across the system.

As for the PSU, 680 watts is more then enough. You'd probably get away with using the 420W that comes with the case infact.

And I'd be surprised if you ever used the floppy drive, I've recently removed my one from my system after realising that I haven't ever used it
