I wanted to replace an older full-sized desktop system, with a smaller energy-efficient and compact unit for general internet web browsing.  A refurbished low cost micro-sized PC seemed like the perfect solution.First the packaging:It came in a box the length of the keyboard, thick enough to also include in it the mouse, power supply, and micro pc.  It appears to be a box just put together by folding over a large piece of cardboard, and it fell apart as soon as I opened one end to remove the contents.  Strike one, but ok this isn't a real big deal.Ok fine, they cut corners in getting the packaging together to keep costs down.I check the power supply and it is not an HP power supply, but some off-brand third party unit. I figure as long as it works, it shouldn't be an issue.I connect the PC up to a monitor via displayport cable, plug in the AC adapter, plug in the mouse and keyboard, and try powering it on.  Nothing happens.  I recheck all the connections and they seem good.  But still the PC won't power up.  I plug in the AC adapter to a different AC on the power strip and try again... still no go.  Bad PC?  Bad power supply? Incompatible power supply?  Strike two... maybe they will ship me a replacement power supply, and I can use my laptop AC adapter in the mean time.Since I also have an HP laptop, and the plug in the back appears to have the same connector, I try my HP AC Adapter from my laptop to try and power it on.  Voila!  It powers up!  The included power supply appears to be incompatible with this HP micro PC.So I try configuring Windows as it goes through the Windows setup screens.  I'm noticing that the monitor will flicker intermittently, perhaps once  every 5-10 seconds or so.  Maybe this will go away once I complete the Windows setup and update drivers, and perhaps use another DisplayPort, as this unit has 3 DisplayPorts.I completed the setup and updated all drivers and firmware (it was already the latest firmware from HP).  I tried all 3 DIsplayPorts and a different DispayPort cable, but the flickering continued.  This appears to be a sign of issues with the micro PC itself.  Strike three!There are just too many issues with this system.  The refurbisher seems to have no QC in place to check for such issues.This was sent back for a refund.
