1- I've read in a few places that it's possible to install a hard disk without moving either
floppy, but I've never seen a source for this. If anyone has any information on that, that would be great as the top slot is kinda ugly as it is.
Yeah, you need the plastic insert that is long since discontinued to make it look pretty. But you sound like a perfect candidate for Larry Pina's Macintosh Classic & SE Repair and Upgrade Guide. It has step by step instructions on how to do this. It's likely on the internet someplace as well.
2- IEvery now and again I get intruiged by 7.5, but I've never actually installed it, as It was quite RAM intensive on my PB.
It is even more RAM intensive on a 68000 CPU and 4MB max. There is nothing System 7
.5 gives you that can't be added to 7.0.1 with extensions, for all practical purposes. Not worth it unless you want to run something System 7.5.x specific.
3- Is there any way to restore the cases original colour?
Search this forum for "retrobright".
4- I would really like to know of any sources for replacement screws.
The easiest way to do this is take a screw from the Mac to the hardware store and match it to a machine screw. Unless you just want to restore it to stock condition, these will be easier to remove without the need for a special torx screwdriver.
