HP Z440 Business Workstation Desktop PC: Intel Xeon E5-1620-3.5 GHZ, 2 X 256GBSSD HDD, 32GB Memory, NVIDIA Quadro K2200, DVD-RW, Windows 10 Pro (Renewed)

With a 700 Watt power supply, 32 GB of ram, and two 6 pin connectors for a video card, this machine has already got it covered for possible upgrading. Easy to change out the CPU. I put in a Intel Xeon E5-1650 V4 SR2P7 3.6GHz CPU, another DVD R/W drive, and a Nvidia RTX 2060 graphics card using the two six pin connectors with a 6 pin to 8 pin adapter. Works just fine! Open hard drive monitor confirms that everything is running cool while running games like Nascar Heat 5 with all settings turned up to best at 1920 x 1080 resolution. No problems so far. I did notice that the old CPU thermal paste was sparse and dry, needed a fresh reapply, and there was a bit of dust on the bottom of the case. Other than that it was ready to go. I will update this review if something dire happens in the future, but so far this is a good purchase.

Bought this to run a second account for popular online RPG.With so much RAM, RAID SSDs and decent video card, I now actually play the game fulltime on this computer to save wear and tear on high end gaming computer.It is quieter, uses less power and NEVER crashes.I love it.

Unit it self works great this units biggest problem is that the power supply connectors are proprietary and does not include a 6pin or even enough sata power connectors to fill the front expansion slots. There is also a large metal piece on the side door that is so large it prevents larger expansion cards like big video cards from fitting

first off was shipped in crap box lose with what might be the worst keyboard ever after less then 5 min of use the paint was gone off 5 of the most used keys 10 min later changed it mouse was no better pure E waste JUNK video card was 100% useless would not even run a movie that i could run easy on a 2003 stock dell , after putting a Gtx 1050ti 4Gb VDDR5 in it worked better but on 5 out of 5 test sites it show 20% to 40 % under what what a E5 1620 should do i got this to play a few games and even with 32gb of DDR 4 ram there was little change it was no better then what i had tiny HP Compaq Elite 8300 Small Form Factor PC with 8gb ddr3 i5 was $100. bucks 5 years ago vs the $290.00 pile this turned out HP dont like to support this the win7 drivers just not there did come with win10 pro and does have big power supply but

Excelente

It is plenty powerful for what I use it for, and I got a great deal for it! I wouldn't recommend this computer for gaming because the graphics card isn't quite designed for it, but as a business computer or something useful modeling, like how I use it for, this is the perfect computer.

installed linux on ssd-s with motherboard's raid, after initial testing, it became apparent something was wrong, extremely slow IO. Destroyed the raid array, tested two hard-drives independently. Turned out one of the ssd hard-drives was faulty. once filled with more than 80GB of data, the writes started getting stuck. After few minutes of waiting started getting disk IO errors. The other hard-drive was fine. If someone is to keep windows on this thing, good luck figuring it out, so beware to test the hard-drives before using it for anything critical.in my case SAMSUNG MZ7PD256 was good, and Micron M600 was faulty

I wouldn't by this system again because it has some problems that as of yet are not resolved by Amazon. The WIFI card isn't working correctly it drops off the connection on regular basis, like sever times a day. So it's necessary to run the trouble shooter program to resolve it and reestablish a network connection. Very annoying. Also have a problem with a USB port that stopped working - the computer has other ports I can use but the one that stopped working is a high speed port. Amazon has offered to give me $20.00 to put toward another WIFI card but hasn't responded at all to the USB port problem. I sent Amazon a response to their $20.00 offer after which I discovered the USB problem and haven't heard back from them on either problem.
