This is a Zotac id40, which I have owned from new, now with 4Gb ram and 60 Gb SSD running Windows 10 ver 204.  I also will include the original 250GB HDD which has a copy of the same OS and software but not fully updated. Original stand and the mount for back of TV/monitor, power supply and DVI to VGA adapter all included.
I have tested the computer on YouTube and it seems to be able to play all 720p video and some 1080p but it drops frames on what are presumable high bit-rate 1080p videos.  It will play 1080p Blu-ray disks with a USB BD reader (not included).
No mouse, monitor or keyboard included.
Asking $500.  Message Joe on 9164 4253 if you have questions.
