First, the parts:
Operating System/ Storage Platform: OpenBSD/custom Slackware build (Cinelive)
CPU: AMD Opteron 4332 HE (x2)
Motherboard: Supermicro H8DCL-6F
Chassis: orig. Lian-Li PC-7H, now Supermicro CSE732i-5o0b
Drives: IDE DVD-RW
RAM: Kingston KVR16R11D8/8 (x4) [DDR3,PC3-12800,1600MHz,Reg ECC)
Add-in Cards: Intel Dual Band Wireless-AC 7260, WBTUO LPE-8CH, AMD FirePro V5900
Other Bits: Noctua NH-U9DO (x2), DeLOCK eSATAp bracket
The symptom is that the system turns on at the PSU power switch with a continuous high-pitch beep (no display or post), which from what I have read suggested most likely a thermal or memory issue. I reassembled a cleaned (isopropyl alcohol) heatsink and CPU with fresh thermal paste supplied with the heatsink. I investigated whether the use of a 4+4 pin connector in one of the 8 pin sockets (both of which are serviced) could be throwing anything off, I removed all peripheral devices connected to the motherboard and played with different RAM configurations to see if one stick was faulty, including switching between hybrid and normal modes on the PSU, to no avail. There are only Power LED, HDD LED, Power and reset switch connections from the case, and having double-checked them I'm convinced I got the polarity right. I'm using only one CPU, it is in the correct socket for this config, as is the RAM in the correct bank of slots. I changed the jumper for SAS to the disabled position.
Any suggestions as to anything else I could try will be met with gratitude. My last resort is to contact SuperMicro support, in case it is something very simple. Hopefully nothing is damaged.
