I love that case. Not sure of how high quality it is since I have never used one but it looks great. The rest of the build looks really good except I would avoid that Raidmax power supply and get a quality brand. Look for ~500w units from Corsair , Seasonic , Antec or PC Power and Cooling. You do NOT want to go cheap on a PSU, it can die and take other parts with it.
I already have the raidmax power. I'm using it with my current pc. I was thinking about upgrading to a corsair 700w. I've also been using the sunbeam case. The case seems decent. Thought I would break some of the pieces assembling it. I had to take it apart a couple of times and nothing has broken yet. Transferred my old compaq parts to it and temperatures dropped around 10-15 degrees. I have not had any problems with the case. Thanks for the PSU warning.
