Came pretty much as described, a 4-core Intel i5-4570 @ 3.2 GHz with 16 GB of RAM.  Interior was very clean when I opened it, not any dust apparent, it looked brand new (picture of interior attached).  It had a 256 GB SSD boot drive and a 1 TB hard drive, both configured properly, and loaded with Win 10 Pro.The included keyboard and mouse were a brand I had never heard of before, "BT".  I didn't bother using them.  The motherboard did not have wireless, but it did have an ethernet jack.There was one problem when I first booted it, the sound would not function.  I went into system/sound and the output sound device was set to "SB220" which normally means a SoundBlaster addon card.  I changed it back to the other output option "Realtek Sound Driver" and then the sound worked fine.The power supply was only rated for 240 watts, so it's a bit small if you want to add a graphics card.  The system was idling at about 30 watts power draw.  The CPU was rated as 84 watts TDP, but I didn't perform a stress or load test.The PCIE slots for graphics cards were half-height/half length, i.e. you can only fit a 7" or 150mm length graphics card (see attached pic).  With the limitation in power supply and graphics slot length, you are probably limited to an Nvidia GT 1030 or an AMD Rx-550 graphics card.  So, if you need faster graphics than that, this isn't the system for you.  The built-in Intel graphics ( Intel HD Graphics 4600, 350 MHz to 1150 MHz) were fine for the simpler games that I ran (King's Bounty Crossroads, Hearthstone and HOMM3).The system is very quiet, I can barely hear it.  I should perhaps have given it a 4.5 star rating since the sound was improperly configured, but it was easily fixed.  Overall, I am very pleased with this purchase.
