What is the better casing: Lian Li PC-7B PLUS or Gigabyte 310 poseidon and what is the best air cooling fan in this list: Gigabyte x-power Gigabyte g-power Gigabyte g-power lite Gigabyte g-power II Thx in advance...
Lian-Li is the world standard of air-cooled cases. It may be a basic unit (low end for Lian-Li), but it is built well. So long as you don't have a lot of parts to install, it is a great case. The only problem is the price...more than twice as much as a similar case from anyone else. As for fans, I can't comment as I have never tried a gigabyte fan.
Ideally none, Gigabyte's CPU coolers are pretty dire (though either of those cases will serve you fine). Go with an Arctic Cooling Freezer series CPU cooler.
