That's a pretty good question: Since I am new-ish to the self-hosting realm, I don't think I would have replaced my consumer router with the Dell OptiPlex 7050 that I decided on. Of course this does make things very secure considering my router is powered by OpenBSD. Originally, I was just participating in DN42 which is one giant VPN semi-mesh network. Out of that hatched the idea to yank stuff out of the cloud. Instead, I would have put the money towards building a dedicated server instead of using my desktop as a server. At the time I didn't realize how cheap older Xeon processors are. I could have cobbled together a powerhouse multi-core, multi-threaded Proxmox or xcp-ng server for maybe around 500-600 bucks. Oh well, lesson learned.

To be honest, nothing.
Running my home server on a nuc with proxmox and a 8 bay synology Nas (though I'm glad that I went with 8 bay back then!).
As a router I have opnsense running on a low powered mini pc.
All in all I couldn't wish for more (low power, high performance, easy to maintain) for my use case, but I'll soon need some storage and ram upgrade on the proxmox server.
I have things scattered around different machines (a hangover from my previous network configuration that was running off two separate routers) so I’d probably look to have everything on one machine.
Also I kind of rushed setting up my Dell server and I never really paid any attention to how it was set up for RAID. I also currently have everything running on separate VMs rather than in containers.
I may at some point copy the important stuff off my server and set it up from scratch.
I may also move from using a load balancer to manage incoming connections to doing it via Cloudflare Tunnels.
The thing is there’s always something to tinker with and I’ve learnt a lot building my little home lab. There’s always something new to play around with and learn.
Is my setup optimal? Hell no. Does it work? Yep. 🙂
I recently did this for the second time. Started on FreeNAS, switched to TrueNAS Scale when it released and just switched to Debian. Scale was too reliant on TrueCharts which would break and require a fresh install every couple of months. I should've just started with Debian in the first place.
I would’ve gone with a less powerful nas and got a separate unit for compute. I got a synology nas with a decent amount of compute so I could run all my stuff on the nas, and the proprietary locked down OS drives me a bit nuts. Causes all sorts of issues. If I had a separate compute box I could just be running some flavor of Linux, probably Ubuntu and have things behave much more nicely
Would've used NixOS
I'd plan out what machines do what according to their drive sizes rather than finding out the hard way that one of them only has a few GB spare that I used as a mail server. Certainly document what I have going, if my machine Francesco explodes one day it'll take months to remember what was actually running on it.
I'd also not risk years of data on a single SSD drive that just stopped functioning for my "NAS" (its not really a true NAS just a shitty drive with a terabyte) and have a better backup plan
Use actual nas drives. Do not use shucked external drives, they are cheaper for a reason, not meant for 24-7. Though I guess they did get me through a couple years, and hard drive prices seem to keep falling.
Run the cables more neatly.
I built a compact nas. While it's enough for the drives I need, even for upgrades, I only have 1 pcie x4 slot. Which is becoming a bit limiting. I didn't think i'd have a need for for either a tape drive or a graphics card, and I have some things I want to do that require both. Well, I can only do one unless I get a different motherboard and case. Which means i'm basically doing a new build and I don't want to do either of the projects I had in mind enough to bother with that.
The only real pain point I have is my hard drive layout. I've got a bunch of different drive sizes that are hard to expand on without wasting space or spending a ton.

I would go smaller with lower power hardware. I currently have Proxmox running on an r530 for my VMs, plus an external NAS for all my storage. I feel like I could run a few 7050 micro's together with proxmox and downsize my NAS to use less but higher density disks.
Also, having a 42U rack makes me want to fill it up with UPS's and lots of backup options that could be simplified if I took the time to not frankenstein my solutions in there. But, here we are...
Probably splurge just a bit more for CMR hard drives in my ZFS setup. I've had some pretty scary moments in my current setup.
Getting a better rack. My 60cm deep rack with a bunch of rack shelves and no cable management is not very pretty and moving servers around is pretty hard.
Hardwarewise I'm mostly fine with it, although I would use a platform with IPMI instead of AM4 for my hypervisor.
