Rated 3 out of 5 by BarryISU from Slow out of box, but fine aft RAM upgrade from 8B It was slow out of the box, even after uninstalling unnecessary apps and updating BIOS, drivers, and all software. I bought an 8GB DIMM off Amazon for $20 and upgraded RAM from 8GB to 16GB. Now it works well. HP should not sell it with 8GB as it is almost nonfunctional. We almost returned it.

Rated 3 out of 5 by Anonymous from HP Prodesk Mini 400 G9 Wolf Pro The Mini is compact and sleek and well designed. However, performance so far is horrendous. Many times the system will take 45-60 minutes to shut down because of system work. What the work is is never clear, but I'm beginning to thing that HP Wolf and other bloatware is part of the problem. Hopefully performance will improve as initial system set up completes, but so far that hasn't happened.

Rated 3 out of 5 by Merkin Muffley from Not my typical HP This is the 13th and latest computer I purchased from HP since 2017. The CPU rips as online benchmarks indicate it should. However upon removing the unit's lid one can see the assembly is sloppy, and the fit and finish of the chassis is amateur. This is NOT what I've come to expect from HP where but only 1 of the previous 12 units revealed any obvious defect upon inspection. Furthermore a sticker on the bottom of the chassis indicates the unit has a 3y/3y/3y warranty in contradiction with the 1y/1y/1y indicated by my online account. For future acquisitions these 2 issues will cause me to consider competitor products.

Rated 5 out of 5 by 8086 from A lot of computing in a little package Don't let it's size fool you. This is the most powerful computer I've had to date, and it keeps my small office very neat. It's about the size of a DVD case and, with Bluetooth, I don't have to be overwhelmed by unsightly cables everywhere.
