Conclusion: Performance in a case is about being able to silently keep components cool. Although no formal testing was done with the Source 210 Elite I can say that the temperatures attained when stress testing were well within normal spec for the E8200 that is contained within this machine.
Pros: Great expandability for cooling, Looks great, Great features for the price, Has USB 3.0 headers, Can hold video cards up to 13" long
Cons: None of the intakes have filters on them, Initial cooling ability could be better, One sided tool-less mechanisms
Summary: Seems like NZXT has gotten their act together. First the Phantom, then the H2 and now the entry level Source. As is the scenario for all cases of this price class, looks is what matters and NZXT has managed to offer a good feature set for a 39.90 or 49.90 Euro chassis.
Pros: Pretty cool looks (subjective), Two fairly quiet fans included, Internal USB 3.0 connector, Choice of two colors: black or black & white, Excellent black & white design throughout the entire chassis, Screwless HDD locks hold suprisingly well, ODD locks hold well, Many openings for cable managemen...
Cons: No dust filters for intake fans, No extra screws included - just the bare minimum, Not many boards have the internal USB 3.0 connector yet, Design may not be for everyone, Simple packaging
