I have 5 workstations. Two with 128 GB RAM, one with 192 GB RAM (still need to complete the build), two with 256 GB RAM.
16 core, 20 core, 32 core and 36 core x 2, all have dual 10 G NICs.
My main monitor is a 48" LG C3 OLED, and two 27" Dell 4K monitors (I don't use them often). There's another 48" LG C2 OLED on the other side of the desk. I also have two more 27" Dell 4K monitors. The Dell monitor image quality is amazing, and even brighter than the LG OLEDs. The LG OLED's can run 4K @ 120 HZ. I currently have four RTX 3090 GPUs, Two 1080 TIs, 21 1070 TIs, 1 1070, 18 RX 580s, and a bunch of older hardware, mining rigs, PSUs, etc. I also have an original IBM XT - the case is banged up. First computer I ever used - started out with a monochrome green monitor, then a Hercules GPU, then a VGA. I even did animation on the IBM XT.
Storage wise, I have a NAS that I have not used, with eighteen 12 TB drives. A bunch of 10G switches. Many NVME drives. Alexa all over the house, WiiM Mini's connected to sounds systems. I love tech.
