First build in a loooong time. Saw BitWit's December RGB build and fell in love with the aesthetic - 'cause you know that's all that matters !kappa.
The graphics card shortage made me think twice about building it but I got a fantastic deal on the Asus Strix 1080 A8G (significantly cheaper than 1070 prices in June/July 2017) so I went for it.
M.2 storage is absolutely lightning quick. I have a hard time getting into the bios as it loads so fast. I timed the startup during a disk check after an improper shutdown and it was 15 seconds - so even quicker on normal starts.
The NZXT case is nice to build in. Plenty of space for the most part except that you will have a hard time locking down the HDD screw closest to the PSU bracket if you've already put the PSU in. The screw labelling could also be better.
I still need to play with the fan curve settings and was dissapointed to learn that SpeedFan does not support the Z270 chipsets. The Asus AI suite is an alternative to the UEFI setup but it's clunky.
The 1080 breezes through everything I've thrown at it at 1080p. I bought this in preparation for Destiny 2 so am looking forward to putting the machine through its paces on that.
The Corsair AF fans really are very quiet and along with the AER and CPU fans provide very reasonable temps at low outputs. My ambient temps have been higher as of late (mid-high 20 centigrade) and the idles have been 38-44 on both CPU and GPU. I know the 7700k runs a little hot and I have noticed spikes into the high 50s when under medium load but overall happy.
The RGB side of things is taken care by the CAM software - which controls the Hue+ and the Quad Lumi CPU cooler. The mobo, RAM and GPU by the Asus Aura software and the keyboard and mouse by Corsair's CUE. It's little fiddly to get setup, but it's a set and forget for me now. I'll probably play with some different settings once I get tired of the current colour scheme. Customisation really has come on a long way since I last built a machine. Ten years ago I would not have dreamed about putting a glass side panel on my case!
