Dell Precision 3420 SFF Intel i7 Desktop

So, when it comes to specs, I only have basic knowledge. Why is this not compatible with Windows 11? Also, what does Grade A mean? If we’re talking milk or eggs, I’m good.

Hey, thanks for the info.

No WI-FI?? How many PCIe slots are in the chassis?

To answer your first question, it’s only not compatible with Windows 11 because of Microsoft’s hard requirement of 8th generation Intel processors or newer (this one is 6th generation). From a technical standpoint, it’s perfectly capable of running Windows 11, and there are workarounds to get it to install and run, but it won’t be supported by Microsoft if anything goes wrong.

No wifi? I didn’t even notice that! :-1::-1:

180w power supply and intel turd graphics? No upgrade path for a gpu even if you find one with the 1/2 bracket.

The processor was pointed out as the hiccup for Win 11, keep in mind there’s a TPM requirement too which I doubt this machine even has an allotment for on the MoBo.

This wouldn’t be a bad office machine if you had the room for it in your home/work office

Always check… even if it’s upright, SFF means “Small Form Factor”. You will be stuck with a computer that you can’t [easily] upgrade the power supply or graphics card.

If you just want a desktop computer that can do Facebook, and maybe some Office suite, this will work, but if you wanted to upgrade this to be a gaming computer, you probably will want a full desktop.

Since I deal with some of these machines at work:

  • No Wi-Fi. Most business oriented computers don’t include them because they are unnecessary in a wired environment.
  • These are sold as workstations that went through ISV certifications, because some companies will not offer support for their software if the computer hardware isn’t certified. That also means everything will be running as spec; no overclocking this one, folks.
  • Integrated graphics got a 180w PSU. If it was originally equipped with a discrete GPU, it got a 240w. The power supplies are proprietary, 12VO.
  • Motherboard uses a C236 chipset; Skylake-based LGA-1151 Xeon CPUs will work. Non-registered/unbuffered ECC memory is supported.
  • Has TPM 2.0 support, but Microsoft still wants an 8th gen or newer CPU for W11.
  • Two low profile slots, x16 and x4. The x16 is adjacent to the PSU, so single-slot for graphics only.
  • Lastly, STOP TREATING EVERY DESKTOP AS IF IT’LL BE A GAMING COMPUTER. This won’t be it. If you want a gaming computer, look for those instead.

You can install USB wifi antenna on any usb port even in the back of case.

CAD, simulation, and rendering all come to mind. Those things all benefit immensely from a discreet GPU. It’s cheeks either way these don’t have either a standardized PSU or a higher output.

This cpu does well with Excel. Good single threaded numbers too. Don’t need wifi in an office setting. WIn 11 can be installed on most anything. Just use the ISO.

BTW Win11 not supported by MS on this? Who cares… who calls MS for support?? Really.

Support means security and stability updates. That is a huge factor to consider. Any vulnerabilities that existed in the final update will continue ad infinitum.

That being said, it’s still good til 2024 for older gear. After that, better go with Unix/Linux. Decent hardware for many use cases, just not Micro$oft approved for Win11.
