Was impressed by how clean the case and the inside was.  You wouldnt really know it was a pre owned.  Its quiet too.  From HP this PC can take up to 32 gigs of Ram.  Was very easy to get going with it.  Everything that was stated was installed.  So far it is well worth the price.  I did get a 3 warranty just for added coverage.  Update.. its been a year now that I've had this.  I have zero issue it.  Im now looking to up grade this for my Flight Sim.  Im now also looking to buying another one.  This OC was. Made in 2012 I think and it seems to still have a lot of life.  The CPU is fast enough fir my needs.  All us needed now is a GPU.  One thing I like about this is, that it has a DVD Rom.  Mostly gaming PC's are getting away from this.  But I feel I can still do everything I need with thus a few more years to come.  I've always come back to HP.  Add-ons are much easier to put on snd run without issues like other brands.
