Seller is GREAT!
Product and delivery were excellent - better than reviews (which were positive). On my upgrading ram, got Blue Screen errors. Seller was very helpful including getting Dell to transfer warranty to me. Dell was not so helpful. I had to escalate, but seller supported with useful info. Strange, because I had found Dell to be positive and helpful in the past. Now operating with increased DDR4 and no issues and xfered warranty and know I'd buy from this seller and recommend without hesitation. His support has been extraordinary and on-going. Not the 'usual' - ship and forget. These guys are easily 10 stars. Thanks again.

Great Computer, badd transfer software
The computer itself is fine. The problem was with the transfer from my old computer. After 3 tech support tries, I was able to make it work myself. The transfer was insistent on moving everything to the C drive sector which had limited space instead of to the D drive that had almost a terabyte of space. I actually had to manually transfer many of my files over. That said, I'm not a gamer and for my needs, it is fast and functional. The lack of a DVD drive was a disappointment, but I was able to get an external one that works fine.

Easiest computer I have ever set up
I am amazed at the ease of setting up this computer. Absolutely loved it. This is my first Dell computer. My next computer...you guessed it...will be a Dell.

HDMI doesn't work - not where to bring it to get it fixed.
WORST investment ever. Do not buy a computer via the internet. This computer only has 1 HDMI - which is needed for the monitor, which works 20% of the time. Out of the box it didn't work, but using different HDMI chords, we got it to work, for a day or two - long enough to throw the box away. Turn the computer off and back on, it no longer works. Again, over an hour of changing input ends, different chords, got it to work. Turn off and back on, same issue. It's not the monitor (tested and checked on other computers). THE HDMI just doesn't work! I can't bring it in anywhere without it costing a fortune. BIG PIECE OF worthless METALLIC CRAP.

Not an micro atx motherboard.
This is a small profile pc. The power supply is not as I expected, not a "normal" desktop power supply with a multitude of connections. Specs are 2 open SATA connectors but there is only one open drive bay for a low profile CD/DVD read/write and no place to add an additional internal hdd.Overall, I am pleased with the performance for home computing.

Nice for the price!
The wife has been working from home and needed a newer computer, I debated between building her one or buying this Dell and after comparing prices I found out that I can’t beat Dell’s price no matter how I diced it. The one I bought has I5-10400 CPU, 8 gig of RAM, 516 SSD, win 11 and WIFI/blue tooth card. Its nice business computer. If you are just running business software, checking email, browsing the net, video conferencing and connecting to work servers, then this computer can do all that and ask for more! It can also handle some video games very nicely. However, if you want to run powerful software like CAD, video editing and consume every pixel in high end games then you need to look for high end computer that is out of this price range!
