I wonder who provides their sponsor money...
As for holding stocking material on a fan: it ain't pretty, but rubber bands work great and you can get some pretty good thick ones that last longer. Make sure you vacuum off your 'screens' occasionally as they can build up dust and such pretty quickly, impeding air flow even more and causing more noise from the fan.
I am a big fan of these Antec SX series cases, too, despite my particularly picky engineering mind. My older Antec KS-188 ATX also came with the optional 300W PP303X and it has a slideout tray... a feature I have had use for only a couple of times. The sliding part has to be done carefully to make sure it tracks smoothly. After building several systems in an SX830 and some SX1030s, I am really pleased with Antec.
I have contacted Antec customer service several times, by fax and by their toll-free phone number, for their free I/O panel and they were very responsive.
