What fits in a 3.5 Floppy Slot


Since I've been getting rid of these floppy drives in my machines, I was wondering what else can fit into them, here are two good candidates:
* "4-Port USB Hub":https://www.rogerssystems.com/store/moreinfo.cfm?Product_ID=765. $20 and it is much neater than an external hub or "SIIG":http://www.siig.com/product.asp?partnum=JU-H41B22&category=USB.
* "USB and Firewire Hub":http://www.cables4computer.com/leftlinks/Product_Links.asp?M1=USB%20and%20Firewire&sub1=Hubs&sub2=USB. $99 and you can get a Firewire and USB 2.0 hub to stick in that floppy port. Made by "Koutech":http://koutech.com
* "Six-in-One Card Reader":http://www.koutech.com/proddisp.asp?page=2&Category=Card+Readers%2FWriters. You can also get a generic six-in-one card reader.
* "2 USB 2.0 plus Firewire":http://www.newegg.com/app/ViewProductDesc.asp?description=17-111-603&catalog=26&manufactory=BROWSE&depa=1. $12.50 from newegg. You have to have firewire or USB headers on your motherboard though.
