Newegg offers the Antec GX500 ATX Mid-Tower Computer Case for $44.99. This $15 mail-in rebate cuts it to $29.99. With free shipping, that's tied with our August mention and the lowest total price we could find by $20. It features two external 5.25" drive bays, one external 3.5" drive bay, two pre-installed 120mm fans, USB 3.0, and a top-mounted I/O panel. Deal ends November 3.
