Just had a look, unfortunately the only lid's I have got have broken screw mounts (I guess that's why they are spare) and I don't seem to have any LCD cables at all.
I'll have another quick look around as I am sure I had more parts than I have found but I am not hopeful that I'll find anything else
Yes, it does have USB and I think I can make out a date of 2000 on the short board plugged into the front.. Looks to have Ethernet, USB and 9-pin serial? The short board also has pins for RX TX and GND. I cannot make out the name on the board but it's something like SW0... V0.3 and it is copyright Apple. So it is made by Apple.
HFSExplorer can write mac floppies on a PC. I did that a lot of times in the beginning when I did not have an ethernet card in my SE/30. But the usage is a little bit difficult and files with more than 1.4 MB can not be used or you have to split them.
