This build is a smallish backup file server that will be the final piece of kit downsizing from my 42U into a 12U rack and two desktop cases. There are a number of similar sized or smaller NAS type chassis available, and the main reason for this build was the price of the case ($59 on NewEgg at purchase) and the fact that I thought I could shove 6 HDDs with little to no modding. The case, motherboard, and CPU are the only parts I purchased for this build, and the rest of the parts are repurposed from other machines. Hardware: Case: Sama IM01 CPU: AMD Ryzen 3 Pro 5350GE Motherboard: AsRock B550M-ITX/ac RAM: 2x 16GB Micron DDR4 3200 ECC UDIMM NIC: No name AQC113 based 10GBASE-T HBA: LSI SAS 9207-8i SSD: Inland Premium 512GB NVMe HDD: 4x 16TB Seagate Exos X16, 1x 8TB Seagate Ironwolf Pro, 1x 8TB Seagate Exos 7E8 PSU: Corsair SF750

The 30 TB model is listed at $2300 USD. https://www.mouser.com/ProductDetail/Solidigm/SBFPFWBV307TOF1?qs=1Kr7Jg1SGW%2BNbgRRG1pe0A%3D%3D&_gl=1*20h1q4*_ga*dW5kZWZpbmVk*_ga_15W4STQT4T*dW5kZWZpbmVk*_ga_1KQLCYKRX3*dW5kZWZpbmVk

It is a pretty small case. I was just using it as refernece to show that if you are going to do a bit of custom work, most any desktop case will work just fine. If you go with the torrent you could get some of these rubber stackers: https://www.amazon.com/SEDNA-Hard-Disk-Rubber-Stand/dp/B07XYBKGWN/ref=sr_1_3?crid=20N040NWGAQVW&keywords=hard+drive+stacker&qid=1690330434&sprefix=hard+drive+stacker%2Caps%2C124&sr=8-3#customerReviews Those require a bit of additional work if you are going to stack a bunch of drives, but in a situation like the torrent, you can install the drives with the cabling facing the motherboard tray. That will make for a nice and clean look, allow the lower front intake fan to cool the drives, and dampen the vibrations from the mechanical drives.

Just made the team switch from my old OCN account. Thinking about dusting off some Windows installs and subbing some benchies for the team. I'll take a look through the hardware pile and see what eligible hardware I have.

How many drives slots do you need/want, 2.5" or 3.5"? It looks like the torrent compact is wide enough that you could stack hdd cages up in the the front of the case. You would just need to make sure that whatever cages you use/print allow for airflow from the side. I would definitely suggest using rubber dampers at all attachment points, but other than that, if you are willing to do a bit of modding you can stuff quite a few drives into most cases. My backup server is about to be transplanted into a 22L case (about half the volume of the Torrent Compact), and that machine will have 6x16TB HDDs, mitx board, 10Gb nic, and an HBA.

A little late on the start, but at least one GPU will be folding for the FaT. --EDIT-- Fired up F@H on the outgoing 2080 Super one last time. +---------------------------------------------------------------------------------------+ | NVIDIA-SMI 535.86.05 Driver Version: 535.86.05 CUDA Version: 12.2 | |-----------------------------------------+----------------------+----------------------+ | GPU Name Persistence-M | Bus-Id Disp.A | Volatile Uncorr.

Life got in the way over the last many months, and I haven't put this router in to production. I am currently just running off of my old EdgeRouter, but I will be putting this build online in the next month or so... Here are some final pics with everything installed and wired up. PiKVM tested and fully functional with the ability to power on/off and access the UEFI remotely. Hardware power and reset buttons are installed behind the front mesh, to the right of the NICs, just to make sure I can't accidentally hit the buttons if I am working on the rack. I am still leaning towards VyOS, but I might ultimately go with OPNSense. I'll post some final pics after it is up and running in the rack.

The final piece to complete my cool and quiet homelab infrastructure rebuild. This case is for my backup server, which will have an ASRock B550M-ITX/ac with an AMD Ryzen 3 Pro 5350GE, 32GB DDR4 ECC UDIMM, 6x 16TB HDDs. Pretty imporessive little case for $53. SAMA-IM01

In Q_Cruncher Out on prizes

I have a few things up and running, so... IN Q_Cruncher You can pull me out of the prize draw.

After battling with some high temps on the HBA, optane drives, and the X550-T2, I finally swapped the fans around on the radiators. Previously the fans were running as intake, and now I have them running as exhaust. In the original configuration, I was never able to get enough front->back airflow to exhaust all the heat that the radiators were dumping into the case. Results from the swap in fan direction are pretty impressive. Temps dropped by 13°C-20°C on the hottest components, and I was also able to drop the speed of the 180mm intake fan by 200rpm.

I did new pads on my 6900XT, but it also got a full cover HeatKiller block at the same time. The pads I used were the same pads I've been using for a very long time on all my cards, which are the Fujipoly ultra extreme. I am just always on the look out for deals, since they are expensive pads. The only card where I saw some major temp drops was with a bunch of highly OC'd 7970's. The workload they were running was basically FurMark on the VRMs. I was able to lower VRM temps by more than 20°C after swapping in the higher quality pads.

Added a few GPUs to the mix. They are not great for F@H, but it will bump up the ppd by 4-5M.

I am folding on a 6900 XT, but not in Windows. For me there is pretty huge range in ppd on various WUs. I see anywhere from 2.7M-6.4M ppd depending on the project that is running. *Edit* Currently folding at 2875core|2150mem

Pretty much what Pook posted, although I forgo the --pause-delay, since I am building from source and that workaround has been fixed in the upstream version. *Edit* Depending on how you're running it, you might need/want to allocate a different amount of memory, but what Pook posted (leaving 3GB available for other processes) should be more or less universally good unless you're doing some other crazy memory intensive things while running stressapptest.

Depending on how close to stable your memory is, it will usually error out in less than 30 minutes, but I usually give it an hour. If that checks out then I'll usually run through a few other stress tests like mprime (Prime95) large FFTs and Blend.

In Q_Cruncher. Out on prizes.

Longtime stressapptest user. It almost always uncovers stability issues quicker and more reliably than memtest. Additionally, there are some other things you can do to hammer the memory and cache to look for instability. Feeding pbzip2 a large (100GB+) mix of compressible and incompressible data (text files, pdfs, jpgs, etc.), has also helped me find edge case instability when dealing with large amounts of fast memory on DDR4 platforms. I haven't played around with DDR5 yet, but the same principles should hold true.

Vulkan compute on this bench is overall substantially better than Geekbench's OpenCL on Linux. The Linux OpenCL score is quite a bit slower than Windows, and I imagine my 6900xt running 2950core/2150mem is clocked higher than the vast majority of 6900xt submissions. Here's an OpenCL compute run for comparison.

Here's my 6900xt on Linux running the Vulkan compute benchmark. https://browser.geekbench.com/v6/compute/187133

Looks good here on Linux on both Firefox 110 and ungoogled-chromium 110.0.5481.100, which had the same issue of the currency sticking to the top of the page.
