I went to get a better case to rebuild a hand-me-down athlon atx mobo system and found this one
http://www.newegg.com/Product/Product.aspx?Item=N82E16811190087
takes a full atx board, has (2) 5.25 external bays and front panel usb/audio. there is another similar case that has front panel firewire too. the size of this thing is really manageable and the price is too. the manuf. web site has a better front pic which looks good as an htpc case. waddaya think?
