Q: Switcher between Mac and PC using 27" Apple Cinema Display

I've been researching mini display port switchers for use between Mac's and PC's.  On the Mac side I have a mid 2009 17" MacBook Pro running OS X Yosemite.  I am in the process of building an Intel based PC (i7-5820K Haswell-E) with a ASUS X99-Deluxe motherboard.  My graphics card is a EVGA GeForce GTX 980.  I want to use my 2011 27" Apple Cinema Display to switch between the two computers.  I came across an older post discussing a switcher between an iMac and a PC.

At the risk of being redundant I would like to confirm that the recommendation of a CS1942 2-Port USB 2.0 Duel View Mini DisplayPort KVMP Switch will work for my situation as well?  In preparation for this I purchased a StarTech 6" DisplayPort to Mini DisplayPort adapter.

I am also using a USB powered Apple Pro Keyboard, Black (one piece of older tech I am holding onto perhaps in vain)  Some of my research states that PC's won't recognize Apple keyboards and that I may need to buy a new one if I want to use one keyboard and the switcher.  I am understanding this correctly?

Thank You
