So my original plan was to take the PSU, GPU, RAM, SSD's out of my current (now old) PC (https://pcpartpicker.com/b/Q2mqqs) and put them in the Phanteks Enthoo Evolv ATX case with a CPU and motherboard upgrade and a new water loop. The only thing I ended up taking was the GTX 1080 Ti so I effectively just built an all new computer. Put an MSI Gaming X 1070 Ti in my old so it was still a fully functioning system.
I use this machine for gaming and work. I work for a software company and specialize in Virtual Design and Construction/Building Information Modeling. We have our own proprietary 3D engine for large scale model aggregation and I work a lot with large model environments.
Gaming wise I play all kinds of stuff but I spend most of my game time lately on Hunt: Showdown and Conan Exiles.
CPU: For a lot of my day to day tasks, especially work wise, single core performance is key and Intel always has the edge here especially when overclocked. It was really between this and the i9-9900k. Hyperthreading just doesn't make a huge difference in most of what I do so I opted for the 9700k. Chip has performed great, as expected, and I've experienced no issues here.
Mobo: This motherboard had all the features I was looking for, as did a number of others, and ultimately the aesthetic of this board won out. It's been awhile since I used an ASRock board and I'm not a huge fan of their BIOS but that's mostly just due to years of experience with ASUS and MSI. The boards been great, I like the position of all the connectors, the on board Power and Reset buttons, and the rear I/O. No complaints here at all.
SSD's: I got every single one of these on sale. I was going to just take the ones of my current system but I went a little crazy on Black Friday and Cyber Monday. The 1TB 860 Evo's I managed to pick up for $127 each. Don't remember off hand what the 970 Pro cost me but after buying the 860 Evo's I wanted a rock solid and blazing fast M.2 as my primary OS and applications drive. Samsung SSD's are fantastic and I use them whenever possible. I've got a number of older 840's that are ~6 years old that are still performing like new and I'm yet to have one fail or give me any problems.
GPU: As previously stated, this is the only thing I took from my other build. I waited to build this until Intel had released their 9th generation chips and NVIDIA had released the 20 series cards with the intention of upgrading to a 2080 or 2080 Ti. Personally, I just don't care about real time ray tracing now. It's too new, won't be widely support for quite some time, and the price premium for this untried/untested and early tech is just absurdly high. The 1080 Ti is still meeting my needs so I just stuck with it. It did feel silly removing the AIO off this particular card and putting it in a custom loop, something better suited for a Founders Edition, but whatever.
Case: I love this case! I've just always really liked the appearance of these Enthoo Evolv cases. I didn't go with the new Evolv X because it's a bit larger and I didn't want the extra size. Also not a huge fan of the LED integration. I do wish this case had a third SSD mount in the back but aside from that I have no complaint.
PSU: This thing is overkill. I'm well aware of that. I wanted plenty of headroom for overclocking and extra power for a second GPU down the line (maybe 2x 2180's? who knows what the future holds).
RAM: A friend of mine had a weird fraud situation occur with their Amazon account and a very long story short they ended up with this RAM kit and didn't even know what it was. Amazon didn't want it back and the thief never picked it up so I took it off her hands for $250 about 6 months ago.
Fans: These fans intrigued me. They offer high static pressure with silent operation and a neutral color scheme without LED's. Be aware that these fans are thicker then typical 120mm and 140mm case fans. The 140mm's at the front of the case actually make contact with the dust filter so for the time being I have the dust filter removed. I think I may swap the front ones for the blacked out Corsair ML 140's in the near future because of this. Aside from the nonstandard thickness, they perform very well and I like that each fan has removable power cables with multiple cable lengths out of the box.
Reservoir: The Protium reservoir is beautiful and I love the Core mounting bracket as well. Singularity Computers makes excellent, but expensive, products. They're based out of Australia so if you're buying in the US be prepared for a long ship time.
Pump: I actually purchased a M7 Plexi/Silver pump from Singularity Computers and then proceeded to lose the thing somewhere in my house. I spent a week looking for it and failed to find it so I ended up picking up this pump from Alphacool. As is the way of the universe, I found the M7 YESTERDAY and will be trying to return it since I never ended up using it. As for the Alphacool pump, the pump top gives you a bunch of inlet and outlet options, which is nice, and the pump functions as expected.
Waterblocks: I liked the aesthetic of the Heatkiller blocks. The quality seems top notch, they look and function great.
Radiators: Not a lot to say here. They're radiators. EK makes good products.
Fittings: Barrow fittings are amazing! I love the way these fittings look and I love the triple O ring design. Each fitting even comes with a fourth O Ring as a spare! Highly recommend Barrow.
Tubing: PETG 16mm OD. I like the look of the thicker tubing but I realize the thinner tubing would have been a little easier to work with. This was my first build doing hard tube bending and I enjoyed the experience and really didn't find it terribly difficult. I know I didn't do anything crazy complicated and I know my bends are not the best by any means but I did all these free hand in a single attempt. I did one just crazy abstract thing up front just to get used to the heating and bending process but it really wasn't difficult and I'm looking forward to doing more of it in the future.
Coolant: I used PrimoChill's Reboot as a system prep agent because I had a bottle of it laying around already. I let that run for over 24 hours, did a few power cycles here and there, and flushed with thoroughly with a few gallons of distilled water. The fluid in there now is from Koolance. I originally planned to use PrimoChill's VUE in this system but I used it in another system had multiple bad experiences. VUE is beautiful but be prepared to clean your loop every few months. Koolance coolant is super low maintenance and contains all the stuff your loop needs to stay healthy and clean over time.
Cables: Custom cables from CableMod. They do excellent work! Almost made my own for this build but that whole process just doesn't look like fun to me.
I had a lot of fun building this thing and I'm very happy with the end result.
