One entry in the budget gaming category is the Antec Six Hundred V2 Mid-Tower Gaming Case. The Six Hundred V2 comes with all of the same features as the original Six Hundred, but with one minor change, there is a 2.5" HDD hot swap bay instead of a 3.5" hot swap bay. The Six Hundred has 3 external 5.25" drive bays and 6 internal 3.5" drive bays. The rear has 7 expansion slots. The Six Hundred has excellent cooling with a large 200mm TriCool blue LED fan on the top and one 120mm TriCool blue LED fan on the rear. HDDs can be front loaded with a removable panel that can also house 2 more 120mm fans, if needed.
