The goal of this build was to build a high-end mini-itx build that can run games at an ultrawide screen - Acer X34 and a constant 100fps.
I got the NCase M1v5 initially, but the case became toasty due to the amount of heat coming from the Asus GTX 1080 ti, and it was a tight fit. I replaced it with Phanteks Evolv Enthoo ITX TG, but there's an issue with the card being 2.5 slots thick - the card pushes the board upwards slightly so I could slot it into the PCI-E slot.
I do intend to do a full custom water-cooled loop by the end/start of this/next year.
I've been building ATX builds for many years now, and it became a such a breeze that I got over-complacent building a mini-itx rig. I'd advise anyone who's building it for the first time to enjoy the build and be extremely meticulous while exercising patience - you'll be rewarded towards the end.
I had fun nonetheless, great build!
If you find this enjoyable, I'll post a hackintosh build featuring the Ncase M1v5.
