Newegg offers the Corsair Carbide Series Spec-01 ATX Mid-Tower Case, model no. SPEC-01 RED LED, for $49.99. This $10 mail-in rebate cuts it to $39.99. With 99 cents for shipping, that's the lowest total price we could find by $9, although we saw it for a buck less last fall. Features include space for up to four storage drives (either 3.5" or 2.5"), five 120mm fan ports (with two being able to accommodate 140mm fans), two dust filters, and one USB 3.0 front port. One 120mm fan is included. Deal ends March 9.
