This was exactly what I needed to use in an AV rack where we added a Micro PC for presentations. It's easy to install and use. You want someone to help you install it on the rack. If you're strong and have a large arm span you could do it yourself, but it's a lot easier and safer for you (and her) with a partner. Plus, it's pretty much plug and play on a Windows PC. I know there is a KVM option, ours was for a PC only so we didn't order it, but I can use it for another application.
