I heartily second the Kingwin 424 series - excellent case if you aren't much worried about price as it comes w/o PSU at about $80. + sh. (newegg and gameve have them). Gameve and SVC also carry the same case under the Beantech name. If price is a significant consideration - look for the Compucase 6A19 series - the same on the inside as the Antec SLK-3700AMB. See coolcases.com for reasons to consider the 6A19 ... Or the Evercase 42x2 series (you can get HD vibe dampers and extra HD cages cheap! from the mfr).
