That's a sweet LAN setup you've got! The only few things that rub me the wrong way is the choice of peripherals and the lack of headsets. Must be pretty noisy in here!
The tabletops also seems a bit too thin and wiggly for my taste, but, honestly, for LAN parties with chill people you personally know — it's ok
As for the actual host setup with a singular disk image — great job! LAN gaming centres do something similar with their setups, with some differences (a lot of centres either use Windows-based diskless solutions that mount vhdx files as drives remotely over iSCSI, or use ZFS-based snapshotting, which is my personal favourite)
But all in all, seems like my dream house :)
I own a chain of LAN gaming centres, so the feedback is definitely skewered into the business perspective quite a bit
