gThumb is a great image viewer but while it offers several ways of sharing images (Flickr, Facebook, etc.), sharing by email is not one of them. Fortunately, it offers a way to call a custom script on selected images.
This is a simple comparison of two cheap mini PCs that run Linux-based operating systems without problems (that is as long as you use a newish kernel) and that are despite the size more than capable of being work stations (not your kind of work, CAD designers).
Fail2ban is one of the ways to prevent script kiddies brute-forcing their way into your system. I find it amusing to view who is trying to get in. Fail2ban doesn’t have a way of listing old bans but it’s easy to get the information out of the logs.

So how do you customize them?
