Last Saturday Mwave, Walnut CA, had a parking lot sale. I pickup a few Inwin IW-S523B cases for $5 bucks each. Although their power supply of 300w seems running fine with one of my rigs (xp2000, asus a7v333, ATI 9700, seagate 72 gig scsi 15krpm), I am not familar with this type of PS. Anybody has any experience with it? Thanks,
