Great build - I initially thought the CPU fan mount was broken but it turned out to have been partially unclipped - either by vibration or snagging on the packing material. GPU support bracket was a bonus I hadn't expected. Initial setup was fine but Win11 update a mess as it seemed to want to 8 or 9 updates at once insisting that these had already been deferred. It stalled at 65% on latest major version. Restarting according to the minor update prompts didn't help. Chkdsk reported uncorrectable errors and DISM stalled at around 60%. Reset via recovery console (Shift - shutdown) ran but dumped me back to the login prompt without changes. I have been here before with Windows update so did a fresh install which ran and applied upgrades without problems. Sorry about the saga but I hope it helps someone downstream, Jim
