I do like how they both look but I don't really like the columns on the second one. Performance wise, are they both about the same or is the second one better? I could live with the columns if it cools better.
I have the coolermaster case you posted (the top link) it is amazing. It is very sturdy, is sleek looking and has excellent cooling ability (especially if replace the stock 120mm on the back). Spend the extra 20 bucks you save on the case and put towards the PSU then put another $20 on the PSU. It is one part that you definitely don't want to skimp on.
