I'm answering to myself here.. I finally got this motherboard and it's been running some services 24/7 for a week now, without problems. With 5.1-RELEASE.
It's no server board (non-ECC ram, no IPMI, re(4) ) but I highly recommend it for cheap silent/low-power systems. A bit faster than Atoms, yet still no speed demon. But it has 6 SATA and supports up to 8GB of ram. And no cpu fan. My office is quiet again. # sysctl hw | grep temp hw.sensors.km0.temp0=51.50 degC hw.sensors.lm1.temp0=28.00 degC hw.sensors.lm1.temp1=39.00 degC Here's the dmesg: OpenBSD 5.1 (GENERIC.MP) #207: Sun Feb 12 09:42:14 MST 2012 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 8167038976 (7788MB) avail mem = 7935467520 (7567MB) mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.6 @ 0xeaf40 (60 entries) bios0: bios0: ASUSTeK COMPUTER INC.
