I Used an HP Z Series i7-12700, 32gigs memory, 500gig Samsung 870 SSD for HexOS and 3 4TB Crucial NVMe drives for 8TB available space. My main system (my first mass produced computer in 35 years) is an Alienware i9-13900K, 64gigs DDR5, RTX Founders 3070TI and 2 WD Black Series 2TB NVMe's in RAID0.
I have an HP SFF Mini handling Scanner web duties for my Uniden SDS200.
My server is an HP G9 ML350, server 2019, 192gigs of HP Smart memory, with 8 900Gig drives in RAID6 (being rebuilt with 2TB SSD's next year) Quadro P2000 (for the Plex server) and it provides shares for the family plus media etc... , the HexOS box will be handling server backups and testing possibly replacing the HP server when they have video card support.
I control the Z, Mini and ML350 locally with a KVM and remotely with Chrome RDP. I'm looking forward to HexOS getting the dashboard locally and seeing where this goes! Hopefully it gets good enough for me to shut down the server some day, or at the very least I can shrink the server size down considerably, we'll see.
