Here are some ideas for the type of mods that would be cool.
-Make a turbo button (blue, preferably) that just increases fan speed or maybe loads the pc with an overclock profile.
-Make those 5.25 floppy drives accept SSDs, to read them when the switch flips and ejects properly.
-Make the monitor click in on top of the pc, just like a keyboard clips on an IBM Portable PC.
Any mods you guys do, I'll be more than happy to check out.
