We Heard You Liked Clusters
Rather than building a big Linux box, I think I might get three of the current Intel NUCs and set up a lab for clustering, replication, and failover testing.
They're pretty fast - faster single-threaded than anything I currently own - and have 2.5GbE so networking is also good. And they take the same memory as my Dell all-in-ones so I already have 64GB for them, and a couple of 1TB NVMe drives I can re-use. So three of those works out about the same as one completely new system.

Plus three of the slim models stacked up form an almost perfect cube - 117x112x114mm.
TP-Link has some affordable switches out - A$360 for 8x2.5Gb and A$500 for 5x10Gb. So all the new stuff I get will be running at least 2.5Gb, finally. We've been stuck at gigabit speeds for twenty years now.

Not a bad idea. distcc on 2.5gb should be decent. Since I'm an anti-intel bigot (ever since those risible MC Hammer ads they ran in the 1990s, along side the "oh right, we can't divide large numbers accurately") I did appreciate the bit you linked about the Asrock 4x4 box stuff some months ago. Very nice little system, takes 64G of ddr4, NVME + 2.5in SATA, and you can remove the wireless/bluetooth module for some power savings. And it's AMD, which makes me happy.

TP link is PRC manufacturing, I think. Should the switches or routers be a concern from a security perspective?

A dumb switch shouldn't be a concern. A managed switch or router, particularly enterprise models, yes. I'm looking at getting an OpenWRT router with this rebuild.

Somewhere in my stash of dangerous hardware is a "dumb switch" that wiped out our office network with spanning-tree traffic, something it shouldn't have been capable of doing.

I hope you safed it somehow.

I made it so safe that I didn't even realize I still had it until four months after I was laid off. It was in the box next to the 10 Mbit hub that we'd found in someone's cube when he complained about Perforce performance. (as for the guy who put a license server under his desk and attached it to what he thought was a switch, but was actually a NAT router...)
