adequate ram and the ssd make this the best desktop of quite a few i have ever owned (i’m a retired computer engineer).  windows reboots in under a minute, and there is no problem of lengthy startup processes hogging the disk drive making the machine unusable.  performance on very large and complex excel spreadsheets, and photoshop image processing is great.  the dvd drive feels rather flimsy, but works fine.in writing this review, the only thing i’m upset about is noticing that all 17 prior reviewers received a free system!
