My first ever desktop build coming from a Razer laptop. Initially planned for a 2080 but I snagged a EVGA 1080 Ti FTW Hybrid for $550 used and it still had two years of warranty on it. Chose an mITX board so I can get a smaller case in the future if future mITX cases with greater GPU clearance come out. Also because I heard all current Z390 mATX motherboards had pretty poor VRMs and this mITX motherboard is renowned for it's overclocking potential.
Generally pretty happy with it, asides from the fact that the AIO tubes get in the way of everything. Didn't expect the FTW card to be so wide.
