1st question - my cpu cooler is the hyper tx3 and I have a choice of either facing the fan down towards the GPU card or up towards the top of the case with little air holes. Which would keep everything cooler?

2nd question - I have a hard drive and want to get an SSD to make everything quicker. Would I have to transfer all of my data over to the SSD from my hard drive or could I just plug it in and it would do it automatically?

Thanks
