Dell’s Inspiron Desktop 3891 doesn’t compromise on computing power as many low cost desktops do. For about $392 as tested, this family friendly micro tower offers a respectably powerful Intel Core i3 CPU, Wi-Fi 6, and Windows 11. Even a DVD burner and a 12 month subscription to McAfee LiveSafe are included in the price. Because of its integrated graphics, Inspiron can’t play many games very well, but it works fine for everyday tasks. With the Acer Aspire TC-895-UA91, a rather more expensive tower with more excellent storage, the Inspiron Desktop 3891 wins our budget desktop Editors’ Choice award for its persuasive case against spending more money on a primary PC.

Respectably Basic

The Inspiron Desktop 3891 is straight forward but respectable. The Dell has a more refined appearance than its pricing would imply; its black shell matches any decor, and its front panel’s cross pattern adds style.

Except for a plastic front panel, the tower is entirely made of steel and weighs roughly 11 pounds. From the back, there is some bare steel.

With sizes of 12.8 by 6.1 by 11.5 inches, the Inspiron is noticeably smaller as a micro tower than a mid tower desktop (HWD). Even though the HP Slim Desktop (S01-aF0020) measures 10.6 by 3.7 by 11.9 inches and is a mini tower, this Dell is more powerful and expandable.

Two USB 3.2 Gen 1 ports (Type-A and Type-C), two USB 2.0 ports from earlier generations, and a headset jack are all on the front panel. They can press the power button nearby. It’s an acceptable option.


A quad core, 3.7GHz (4.4GHz turbo) Core i3 10105 processor, Intel UHD 630 integrated graphics, 8GB of RAM, a 256GB SSD, Windows 11 Home, and a one year warranty are all elements of the $392 Inspiron Desktop 3891 from as reviewed. A USB keyboard and mouse are also included, along with a 12 month subscription to McAfee LiveSafe anti malware.

The optical mouse is a straight forward three button device that also does the job in the bare minimum. The slim style keyboard has pleasant keys and is functional.

The Core i3 10105 is a minor frequency upgrade for Intel’s Core i3 10100. This Core i3 was introduced earlier this year along with Intel’s 11th Generation “Rocket Lake” processors. The least expensive Rocket Lake CPUs released by Intel were Core i5s; these and a few other modestly upgraded 10th Generation processors were marketed as “Comet Lake Refresh.”

Dell Opened

The performance of this 65-watt CPU is significantly better than that of Intel Celeron, Pentium, and AMD Athlon processors. With a desktop this cheap, you must still be realistic in your expectations. The desktop’s 256GB solid state drive is under sized, and multi tasking quickly exhausts the system’s 8GB of memory, causing the desktop to become overloaded sluggishly. Fortunately, the memory and the on mother board storage can be boosted (adding an 8GB stick of DDR4-2666 would only cost around $30 at after market prices and provide very better performance). You can only play games that use integrated graphics in terms of gaming.



All you could ask for in a low cost desktop performance is provided by the Dell Inspiron Desktop 3891, plus a bit more. It has a quad core Intel Core i3 CPU that gives it plenty of performance, Wi-Fi 6, and a DVD burner. Its lone HDMI port and support for just one internal storage drive are its most significant draw backs. Integrated graphics further curbs its gaming powers. However, if you only need the basic computing tools, this Inspiron compact is a great deal and wins the Editors’ Choice award for low cost desktops.
