Question YOLO?

This build will make very little sense from a price-to-performance POV, but we think it will be an interesting journey.

We don't have any specific goals (yet) other than to have fun.

We haven't built a long-term computer in a very long time, so we will keep this setup for five years. (That way we can kinda justify the costs involved!)

We are toying with the idea of liquid cooling. We will first see how well the system does with air cooling.

If you have any questions please ask. Also, we appreciate tips and suggestions.

We will list the prices we paid for components including shipping and taxes. We think that in a few years this data will be fun (?) to look back on.

What we are building will not have bleeding-edge hardware. Our number one priority is stability/reliability. We won't be overclocking except to run the memory at XMP.

Our thought process for all of this is a bit weird. Over time we will try to explain why we are choosing specific components and stuff.

Maybe a naive question: but how would such a high end build rank against a server-class build (and with ECC that comes with it)? Have you considered to build a server?

Goes without saying: that is an intimidatingly gusto build.

The big ticket item we have wanted to close off on was Wayland, because while Wayland has been production ready for most of us for a while, there was still some cases it didn’t cover as well as X.org. The biggest of this was of course the lack of accelerated XWayland support with the binary NVidia driver. Fixing that issue of course wasn’t something we could do ourselves, but we have been working diligently with our friends at NVidia to help ensure everything was in place for them to enable that support in their driver, so I have been very happy to see the public reports confirming that NVidia will have accelerated 3D in the summer release of their driver.

We did the ECC thing last year with the 1920X build.

Enterprise-level hardware gets really exotic and really expensive really fast.

We are looking at this as a HEDT/enthusiast computer, with slightly exotic hardware. Maybe top-of-the-line-but-not-server stuff?

Enthusiast hardware looks cooler, too.

Go on aliexpress and search "LGA 2011 set".

The idea is that after the "spectre" issue, as well as Intel launching their new series of Xeons (E7, etc), the market was "flooded" with E5 v1, v2, and v3 Xeons that you practically get for free. I mean, they have wagons full of such toys (both second hand and new) which they sell for scrap or melt to recover the gold (which is not really profitable...). So some "entrepreneurs" decided to make cheap mobos for them, to sell them (in fact, to sell their mobos!) and you can get a full "set" (mobo, cpu, plus ECC RAM !!) by only paying the price of the mobo. That means, like 90 bucks for the whole set, including a 8-cores E5-2450 v2 Xeon that runs at 3G3 and 8 gigs of ECC RAM. If you afford to double that price, you may even get a 12 cores and 16 gigs of ECC RAM. Some people here bought them and they really fly at LL and P-1. The only issue is that they are power hungry... Of course there are some risks, and there are known problems with the mobos (did I say "cheap"?) like for example the SATA are too slow (there are many youtube videos that discuss the issues and the risks, try the same search, or try "lga 2011 vs lga 1356" on youtube). (edit: yes, read well the descriptions, when they say they ship the cpu's "random", you may get a lga 1356 with your 2011 mobo, which would be a serious waste).

You buy 10, add some coolers and a shelf, and you have a 80 or 120 cores machine for a thousand bucks, crunching primes and melting your kilowatts...

Less of a problem for Mike than most - he pays 1/3 as much for electricity in backwater Arkansas than I do in high-tech/woke/green/blahblah California.
