Nice! So it has two floppies AND a hard-drive? Looks like some aftermarket side mounted setup. I heard such a configuration wasn't officially supported by Apple at the time. 
MacOS 7.5? I personally wouldn't recommend running 7.5 on a SE. (I tried it on my Macintosh Classic way back when I used to have one. Was not a good experience) 7.5 eats a lot of ram and with an SE 4mb won't get you far with MacOS 7.5. Not to mention it will probably be pretty slow to do anything. If I get an SE/30 then I would certainly try and run 7.5.5. She could probably handle it. But an SE would have some trouble.
Latest I'm planning on running is 7.1.1. But if that's a bit too much for her, I will just fall back to 7.0.1 or 7.0. MacOS 6 is a bit too old for my taste and don't really plan on running that that OS. Only time I might is if I ever get a Macintosh Plus/512k/128k where running 7.0+ wouldn't work out well.
(although if a Plus could handle 4Mb of ram and I have an external hard-drive for it, I may try and run MacOS 7 on that too. )
