HP Z440 Business WorkStation Desktop PC: Intel Xeon E5-1630 v3, 2TB HDD, 32 GB DDR4, NVIDIA Quadro K420, DVD-RW, Windows 10 Pro (Renewed)

It may not be suitable for every game, but so far I have been fine with all of the games I played on it. It is only Windows 10 capable, meaning it doesn't have other hardware necessary to upgrade to Windows 11. But I am fine with this computer for everything I use. I even have my ebooks written on this one. I am a writer who does his proofreading and editing of my stories. And the computer fulfills all my needs for the time being.

The computer tower was a little delayed in shipping, but when it arrived it was packaged very securely in styrofoam. My older HP Tower had been freezing up. I could not access the Start Menu and my desktop icons even after taking it to a repair shop. This computer is very fast and has all the bells and whistles I need for doing graphic art and musical creative projects.I am a little annoyed with a message I keep getting on the desktop everytime I start the computer. It reads:"Your version of Windows 10 is out of date. Your device is running an older version of Windows 10. To continue to receive security updates and enjoy the latest features Windows 10 has to offer, you need to update your device to a newer version of Windows 10.*" As far as I know this is a "newer" version of Windows 10. I went to security updates, and I'm up to date! I also went to the H.P. website and downloaded their program for maintaining the computer. I found out 6 Drivers were out of date, and there were other critical updates that needed attention including the "BIOS", which is the problem I was having with my older computer.After scouring Amazon for a Windows 11 upgradeable PC, in customer reviews and questions people mentioned that it was upgradeable or they had already upgraded and had no problem. I know Windows 10 is useable for a couple more years, but their criteria seems inconsistent. In their list of criteria to upgrade to Windows 11 they have listed a minimal processor speed of 1GHZ. This computer has a 3.70 GHZ processor, and is on another list of theirs as being acceptable. What is it? Acceptable, or not acceptable? The other is the TPM needs to be 2.0, not 1.2. It's very confusing!Other than those glitches this is a good computer.

I purchased this decade-old system to centralize my home lab. It performs exceptionally well with Proxmox and offers affordable, upgradeable memory modules. I replaced the processor with an E5-2699v3 for less than $50 and added 256GB of RAM. Although it may not be as power-efficient as modern systems, it’s quiet and easy to rack-mount. Considering its affordability, it’s an excellent investment.

Great systems for the upgrader! Mine arrived clean, with a recent BIOS and the 700w PSU and the lower front performance fan installed. W10p retail version, woot.Thank you ConfigureSystem for a clean refurb that adds value.[And thanks Amazon, for shipping it to Alaska]For those who don't know, you can update to the 4/23 BIOS at HP's support site and drop in most any Xeon E5 16xx, 26xx, or 46xx V3 or V4 CPU from here or eBay.You can also drop in 8x32gb sticks of 2133 with a V3 cpu, or 2400t ECC quad-channel ram if you upgrade to a V4 Xeon. 22c/44t Xeon with 256gigs of ram. 8DThere's also 2x PCIE3 x16, and a 3.0 x8 slot on the PCI bus, and 3x PCIE 2.0 and 6x SATA3 run by the Intel C612 chipset. Motherboard was built by Supermicro for HP.Downsides to this rig are few. The single-fan cpu cooler is good for 145w TDP, but not 24/7 [HP made a vapor cooler, but they're rare and precious on the aftermarket.]You'll want the not-cheap Memory Cooling Solution if you install >4 sticks of ram. You can jumper the 6-pin connector per youtube to avoid the POST code, but you'll never feel right about it. The cpu cooler dumps heat on the aft sticks. You can feel it and hwinfo will show it.The BIOS, while updated by HP in 4/2023, isn't as nice as the ones in the Z640 and Z840.The 92mm rear case fan will need help if you drop in a 3090, or any modern GPU that doesn't use a squirrel cage fan and exhaust out the rear. Case cooling is definitely the bottleneck.But it's not superhard to remedy. Nor are case swaps...

Had trouble with this machine from day one. On day two, I had actually printed a return label to send it back and decided to keep trying it. Sometimes it would work and sometimes not. Out of the box from the beginning it always had a message in the top left corner anytime the power went off then took forever for it to come back online. I kept working with it because i needed it for work and it finally quit working completely after less than three months.DO NOT BUY ONE OF THESE MACHINES

I never write reviews but felt like I needed to with this one. I gave it 5 stars because you definitely get a good budget server. I grabbed a 240gig SSD and reused the 2 tb one that was given. Its a Toshiba 7200rpm drive so a fast HDD. I grabbed a more core cpu on eBay for about 30$ so all in im at 260$ for a proxmox server. I ended up using Ubuntu to run Pihole on, Minecraft server, network controllers, and some other work-related mid-servers. This thing works very well with them. I put also Truenas scale on it for the best of both worlds. It has a 1gbe onboard, so you won't get 10 gbe out of the box however just go and buy a 10gig nic from eBay for 40-50$ and toss it in there.Note the Display port on the GPU didn't work so I had to get a DVI cable to HDMI to work with a newer monitor. For a 10-year-old machine and an SSD this thing rocks and got a 14-core CPU from EBAY to make it work even better. Amazing find recommended by a friend.Great machine for testing

Arrived with a dead dedicated GPU, not that hard for someone who are planed on switching out the GPU to begin with. But for someone with little to no experience, might be difficult to troubleshoot
