Built a small machine using an Asrock N100DC-ITX motherboard, it has an Intel N100 built in and I also have 1x NVMe and 2x HDDs. The board has a DC Jack so no external PSU.

First time I booted it, the NVMe had Opensuse on it so I played around a little, no problem. When I boot into BIOS also no problem.

When I boot into Unraid, there is a strange sound coming from the back of the board, sounds like an interference sound. I cannot tell if it's coming from the ethernet port or from the power DC Jack. I think it's from the power.

I recorded it with my phone and bumped the sound +20 dB, this is how it sounds like. You can hear the fans and that sound. https://soundcloud.com/user-300866676-719653331/n100-1

For power I tried using both an Intel NUC 65w power adapter and an Asus laptop 90w power adapter, the one Asrock recommends on their website. The system has been running for 1-2days, with 4 containers and Home Assistant VM, it idles at around 16w. Without Home Assistant, it drops to 11w.

Any idea what that sound is?

Edit 1: If I go into BIOS and turn off Intel Turbo Boost Technology then it is silent but also kills my performance?

Edit 2 So because I did not want to leave Turbo Boost on, I did some more digging and also realized my CPU was always boosting in Unraid. using "watch grep "cpu MHz" /proc/cpuinfo" it was almost always between 2900Mhz and 3300Mhz. I installed Tip and Tweaks plugin and set Normal CPU Scaling Governor to power saver. The sound is gone and now it seems the CPU goes all the way down to 600 MHz and up to 3400MHz depending if it needs it. I don't know if the power saver will affect performance in any way but so far so good and I don't have hear that wheeeeee anymore.

The Asrock N100DC-ITX uses a 19v power brick so no separate PSU to power the drives. It comes with a 4 pin cable that splits into 2 SATA power.

The case I chose, Silverstone SG13, comes with a 3.5" HDD bracket but you need to mount the drive belly up so you can screw it in. The second drive I want to put where the PCIe slot is, found a nice 3d model for that. The thing is, the power cable would be too short and the drives would be too far apart to reach both.

So I removed the HDD bracket and cut 2 L-shaped aluminum stripes and I screwed the drive belly down. This way the cable now reaches both drives. I know, I could have cut the cable and made it longer but I prefer to avoid playing with power cables if I can.

Turned out quite good. Wanted to share it with other people. Now I need to find someone to 3d print the PCIe HDD holder and find some rubber stuff to put under the L-shapes to dampen the sound of the drive. This is the 3d model, https://www.printables.com/model/385403-pci-slot-hdd-bracket but V2 with the nice feet.

PS the drives in the images are broken so I just used them as dummy drives.

That's about it.

It's a guy playing the beginning of the game, it's filmed in vertical with the phone :) Will most likely be taken down very soon.

I didn't watch the intro, just skimmed through the gameplay parts, looks really good.

Had an exchange of emails with someone, around 4-5 back and forth emails. He then told me that my last reply never arrived. When I forwarded that email again to him, he told me that actually the original reply arrived but landed in spam... he checked it after I forwarded the initial reply.

It's not critical or even a super important conversation but I think he lied to me. Is there any chance that a reply lands in spam if the last 4 mails in a thread arrived without a problem?

The emails were sent from a custom domain, using Office 365 Business. I have that email address for more than 6 years and I never had a problem with my emails landing in spam or never arriving. It's the first time I am hearing about it but I think he is duping me.

Edit Thanks all for the replies, it's good to know that it can happen.

It's incredible how much the prices have fallen and that's how it should be. Sure, I bought the 960 close to launch but still the difference is staggering.

The 960 Evo still chugs along albeit it's a new one because a few months after I bought it, I had to RMA it. I guess that's what happens when you are an early adopter. I lost a few hours of work when the original 960 Evo decided to stop working but it also taught me to be more paranoia with backups.

I saw the new motherboards coming out with the N100 processor and I think it would make a great little NAS system.

This one has 2x SATA connectors but then it hit me, if the mobo doesn't have a 24-pin connector, how do you power the Sata drives? So far I've only built PCs with a regular PSU so I never wondered.

I think it might be a stupid question :)

This is the mobo https://www.asrock.com/mb/Intel/N100DC-ITX/index.asp#Overview
