hmm i like both of the coolermasters. i also might add that im a noob at building pcs from scratch, so i would like it to be easy assembly if possible. the most ive done is install ram, and pci-e cards.
Here's a good link that will give you some tips on the correct steps to building a pc. This should help...
I used a link like this almost 5 years ago and now I have a computer business on the side. Read carefully and be cautious and you will be fine. It's actually quite simple with the "plug and play" features compare to the old days.
I would go with the 534, I would have bought that last week if it were that price with free shipping. I got the 690 on ZipZoom for 60 free shipping. Offer is over now.
