Generally it all comes down to how much money I have left in the budget after buying all the parts I want. For the most part I'd put the money into other parts before the case and just by an NZXT Source 210/210 Elite. For $50 the Source 210 Elite is an amazing case, and all most builds need. The only down side is there isn't enough room for a dual-120mm radiator at the top of the case. But for my personal rig I just had to go with the 650T, but I already had all the hardware I wanted, but my old case was...well...old, and I wanted something new that I knew I would like for several years(my old case was 5 years old).
