Rated 4 out of 5 by Reviewer J from HP Pro SFF 400 G9 Desktop PC Review The best thing I like about this PC is the improvement in the speed of the performance of the whole range of actions requested, so far. Given that this is a compact PC, it would nevertheless be a lot easier to work with it if the spacing of the USB drive openings were a little further apart and especially if the labels or wording on the PC were larger and more easily readable.

Rated 1 out of 5 by HP knowledgeable User from Stay away from HP Website description for their hardware is vague enough to mislead you into buying the wrong equipment. Their customer service stinks. You have to wait for hours, then you get bounced around from one person to the next, and none of them are able to resolve your issue. Then you try to return the equipment that did not work for you, and they decide to keep 15% restocking fee, for deficient equipment that you never could use.

Rated 4 out of 5 by Miss TJ from New office computer after 20 years. Took a bit of time getting used to new buttons, etc. with W11. Graphics and speed are great. The DVD is not the same quality as my old computer, but I will be careful. Had to purchase a spliter for two displays, as only one hdmi connection. Very quiet and compact.

Does it have a CD unit?

Asked by: Deb829
Hello, Deb. Thanks for your question. When you select Customize and Buy you can select the DVD-ROM or DVD-Writer under the Optical drive section for this HP Pro Small Form Factor 400 G9 Desktop. If you frequently need to write or burn data to DVDs, the DVD-Writer would be a more suitable choice. On the other hand, if you only need to read DVDs, the DVD-ROM would suffice.
