i decided it's finally time to post my setup here. this is pretty temporary as i plan to add a side desk for the powermac on the right side in the future, but for now its set up like this. the left monitor as well as the razer keyboard and elecom trackball mouse is hooked up to my desktop PC which has a ryzen 5 2600, 16gb ram, an evga gtx 1070 ftw2, 500gb boot ssd and a 9tb windows logical volume for data.
the apple monitor as well as the apple keyboard and mouse are hooked up to my powermac g5 quad which i just acquired a few days ago (you probably wont believe this but one of my online friends very generously gifted this to me, along with 3 video cards to go with it, and a bunch of software cd's and other stuff, and his only condition was that i would make a video about it to upload to youtube) which has the original liquid cooling system, still intact, along with an ati x1900 video card, 9gb ram, and a 1tb hdd, which im thinking about possibly upgrading to a quadro fx 4500/7800 gtx, 16gb ram and 2tb hdd in the future, although i'm not sure if it would really be worth it for the amount of performance that i would be gaining.
computers from left to right (under the desk) are the g5 quad, my dell t3500 headless server which has a 6 core xeon x5680, 12gb ram, a 320gb hdd and a nvidia gtx 780 ti, completely overkill since all it's currently running is my website

, and then on the far right is my main desktop workstation
