I don't know how to start this one. It's been few years since I modded anything and posted it to this forum. Well, I guess it's story time. At the beginning of 2017. I decided that it was time to buy myself a new (used) PC. I was mesmerized by HP Z series workstations and I bought Z600. Decent rig, but it had it's problems - it was noisy or hot, depending of fan speed. I decided it had to be transplanted to normal ATX case and properly watercooled. So, I bought Cooler Master Cosmos case and additional Z600 motherboard. Few holes here, few standoffs there and weird MBO found it's place inside Cosmos.
