I actually did a _very_ similar build in an HL8 chassis earlier this year. It’s also running TrueNAS as my offsite NAS backup. 🙂

> While I’ve been waiting for the HL8 to go on sale and enter production, I’ve been debating the “Full Build” or custom “pro” build in the HL8 chasis. In fact, I came up with “pro” and “pro max” options with what I’ve been able to find for sale here in the US. It’d be awesome to hear from others on these. Definitely, let me know if there’s something I’m not considering or just your thoughts in general. I’m defining “pro” as the following: Motherboard/CPU that supports ECC RAM Remote Management …

I’m a big fan of the AsRock Rack X570D4I-2T motherboard. It’s worked really well for me with 10G networking, four slots of ECC memory support, and integrated BMC provides management features plus onboard VGA graphics. I can also confirm the 4x4x4x4 option is available in the latest 2.5 BIOS in my setup.

One note for you, you’ll need to remove the CPU back plate from the motherboard in order to install the fan you bought. I documented doing that midway through the comments. It’s easily doable with a little bit of patience.

I’m looking forward to your findings with 5650GE ECC support. You’ll see my in build post from above that there was also a lot of speculation on which CPU’s would or would not support ECC. Since it’s a PRO CPU, I think it _will_ support ECC as well as integrated Radeon graphics.
