It's a nice little computor for the money.  Here are some things you need to know:1. No HDMI.  It has VGA and DVI video outputs.  You can buy DVI to HDMI adapters fairly cheap.  About $5-10 USD on Amazon.2.WiFi isn't original, it's a USB stick that came with it.  I expected to use a hardware connection (which it has) so I'm fine with that, although it does seem a little slow, it was nice of them to add that.3. Came with a keyboard and optical mouse!  Not expensive, but functional and unexpected nice touch.4. Mine didn't have an internal Optical drive, it was USB-powered and external.  If you use it, you might want to order a USB multiplier as well.5. If you have an old favorite keyboard and mouse, the ps-2 connectors and a 9-pin serial port are on the back.6. The BIOS on this machine is August-2014, so has been updated since manufactured.Now, about that problem:  it appears the hard drive failed when I rebooted (after spending a couple hours configuring Windows and getting all set up, and after business hours for AST/SkyTech ... Major Bummer!Amazon tried to provide help but from Lenovo, who has no idea about the current configuration of the computor, and the original warranty is long expired anyway.Going into the boot-up (Power-On) menu didn't reveal anything wrong, but the hard drive did not show up, and the drive constantly makes soft clicky noises, like it's searching for the boot sector.  So I think I had a hard drive failure!  According to Lenovo,  there's a diagnostic mode as well, but I can't seem to find it.I will update this review with the results of customer service, hopefully tomorrow!Update, 3-APR-2021:No response from Skytech or ASTsys.  Called them 3 times, never got through to anyone.  Voicemenu says the standard "Due to high call volume, blah blah blah...".Found the diagnostic mode.  F1 key held on boot-up gets you in.  It can't see the Hard Drive at all.I ordered a replacement computor, but if i turn it in with a hard drive that has my passwords and other personal info on it, what then???  Now I need to wipe the drive, but can't if the boot sector is gone.  It's well known that data can be recovered with special equipment and software even if the boot sector is gone.Very concerned at this point, and not happy.
