Perfect for most people. Not a gaming or heavy processing computer but it great for everyday use.

Bottom Line.. The three I purchased came in original HP packaging with HP mouse and keyboard. Bottom of the box opened so seller could add their marketing. Brand NEW old stock AMD 5000 series core. Last Gen at 33% the cost of HPs latest offerings! I would buy more if I could afford it.

The computer works fine, after I purchased a clover leaf extension cord to use with the power supply. Normally, something so basic is provided with the purchase.

Great little computer with full features. Just the right size to fit a small desk.
