DFI DT122-BE 2nd Gen AMD Embedded R-Series Industrial Desktop Box PC 2.7GHz HD ! | eBay
Overview:
These Industrial ITX machines are based on the same AMD APU SoC as the capable HP T730 thin client. This is a quad core 2.7GHz board with boost clock rates up to 3.6GHz. Typical idle power in Linux with a single SSD, 16GB RAM and a Mellanox Connect-X3 VPI NIC is ~25W. That's around 5W more than the (extremely power efficient) HP T730. Not too shabby for a commodity parts ITX box.
For some context, the T730 thin client is selling for around $160-$200. At $100 or under this is, in my opinion, a very solid purchase.
Why is this machine exciting?
- Average power draw before add-in hardware is under 20W at idle running modern Linux
- (2) 1Gb NICs: Intel i210 in addition to a Realtek r8168
- One full-sized 16x PCIe slot
- one mSATA/m-PCIe slot
- You can jam at least 6 2.5" drives in the case if you're creative
- SATA/mSATA ports aren't shared, you can run 5 drives by default
- Runs Proxmox well, and can easily handle two (or more) pfSense VMs without breaking a sweat
- Routes gigabit internet like a champ
- AES-NI equivalent
- AMD IOMMU Support
- Under 2U, fits nicely on a shelf
- 250W Delta FlexATX PSU

Noise/Volume:
Just a heads up, these are significantly louder than the T730. The factory 40mm exhaust fan is annoying, but easily replaced with a $5-10 Sunon or your favorite alternate brand.

PSU is a 250W Delta FlexATX that's quite a bit nicer than I expected given the low price we're paying for these machines:

IOMMU BIOS:
Update: Thanks to user
@mimino DFI has provided a BIOS that enables IOMMU,
see post here. See just below for a copy with updated device firmware included as well. This will allow you to use up to 8 VFs per SR-IOV compatible device. SR-IOV support is a bit dodgy though, I wouldn't plan on using it for anything important.
Quieting the Beast:
Edit: I have a selection of 40mm Sunon Maglev fans here, the ~9CFM model works nicely as a replacement. I wouldn't go much quieter/lower CFM if you add a 10 or 40GbE NIC like I did.
The stock fan is an Everflow R124020BM:
- Rated Current: 0.16 Amp
- Rated Input Power: 1.92 Watt
- Rated Speed: 8000 rpm
- Maximum Air Flow: 10.19 CFM or 0.29 CMM
- Sound Level: 34.8 db(A)
I've swapped the fan in mine for the Sunon MB40201VX-000U-G99 and it's a perfect drop in replacement. Audibly it's around 1/3 quieter.
- Current Rating 115 mA
- Power Rating 1.38 W
- RPM 8200 RPM
- Airflow 10.8 CFM
- Noise 27.5 dBA
The Sunon MB40201V1 is an even quieter and lower power option, at 25dBA a V1 is approximately half the loudness of the stock fan. Temps are good, and you could definitely go even lower speed if you're intending to use your machine for a low intensity application.
- Current Rating 70 mA
- Power Rating 0.84 W
- RPM 7200 RPM
- Airflow 8.9 CFM
- Noise 25.5 dBA
V2's and V3's also exist, but I'm not sure I want to go that low speed with a Connect-X3 in the case.
