Unidentified beep code - 3 low 2 high X 5

[REDWINGZERO]

I've got a brand new ProDesk 600 G2 Mini, right out of the box.  I connected my wired USB keyboard, a separate USB wireless mouse, a standard VGA monitor, and an ethernet cable, and tried to boot.  When I power the unit on, I get nothing on the display and the power button blinks red, accompanied by 3 long, lower pitched beeps, then switches to white, accompanied by 2 short high pitched beeps.

At first, after searching some forums, I thought it may be the VGA input.  Maybe the VGA isn't active since there's also a DisplayPort connector.  I switched to a different monitor with a DisplayPort connector, and still no joy.  I then thought it may be the keyboard and/or mouse, so I disconnected those, and started up again.  Same results.  I've popped open the case, and without disassembling the entire thing, I can't see anything that jumps out at me, indicating an issue.  I've scoured the forums for that beep code, but can find nothing related to this model and that same beep code.  Anyone have any ideas?

According to this HP thread, that beep sequence means a hardware memory problem:  http://support.hp.com/us-en/document/bph07107?jumpid=reg_r1002_usen_c-001_title_r0001
