Just as other recently reviewed sub-$300 desktops, the Dell Inspiron 3668 desktop is a regular low-mid-tier desktop meant for home and office duties. It is meant for the casual user with regular tasks such as web browsing, daily computing tasks, media handling, and office-related duties.
- Simple design and aesthetics
- Plenty of room for expansion
- Decent amount of ports
- Middling performance
- Great value for the price
- Ample storage – 1TB HDD 7200RPM
- Easy to set up system – plug and use
- Lacks SSD
- Slow bootup
The Dell Inspiron 3668 sports a simple design, nothing like the Alienware series gamers are used to. But it shines in its own subtle light. For the most part, it should be a gem for the modest at heart user looking for a budget desktop with an impressive performance. We recommend it as our sub $300 Editor’s Choice for budget-entry-level desktop use.

Design and Features
Design-wise, the Dell Inspiron i3668-3106BLK-PUS strikes a good balance between style and restraint. The front chassis is made of polished matte black case that enshrouds a metal case within. Its edges are finished with silver lining running along its whole front section.
Meanwhile, the embossed silver Dell logo sits close to the bottom of the face while a neat mesh-like assembly of vents adorns its south. Moving on, the side panels are both made of hard plastic with no vents are present (there is one at the rear) like as is common for some desktops we’ve reviewed in the past.
I’m looking at the CyberPowerPC and iBuyPower desktops with see-through plexiglass side panels. Nonetheless, considering this Inspiron has no graphics card. As a result, there isn’t much heating that should cause worry so the rear vents are enough.
Getting into the hood requires not much effort too. The rear has a few screws so you need a Phillip’s screwdriver, a little workman skill and a few minutes to get through. Inside, there isn’t much to look at either The arrangement is nothing special, in fact, a little bit disorganized but it’s put together for functionality (it’s bearable).
Upgrading some extra components is easy as there is space for expansion. Cabling was clearly not their strong suit but at least you can get around to whatever you want easily. For storage, there is a single 2.5-inch hard drive and a 3.5-inch bay for expansion.
Measuring at 11.93 x 6.06 x 13.9 inches and 13.39 pounds the Dell Inspiron i3668-3106BLK desktop is a pretty moderately sized PC. Compared to other towers we’ve seen, it takes on a smaller footprint. It shares a similar shoe size as the Dell Inspiron 13650-1551SLV desktop, but it has a trimmer compact small form factor size compared to the XPS Tower Special Edition PC (15.22 x 7.09 x 14.02 inches).
Dell managed to fit in a couple of ports in this PC, but I must say most of them are just the basic ones like everything about this entry-level desktop. The front section houses two USB 3.0 ports, a microphone jack, microSD slot, power button, and Optical DVD-RW Drive.
Now, the microSD is a good touch to this computer and should help you load photos and video from your camera should the need to transfer arise. For the USB 3.0 ports, they are just as basic as the rest of the other components and should get you by without qualms. All ports considered, the USB 3.0 port is the one best option you get if you want to transfer data faster.
On the flip side, the rear side offers the bulk of ports. You get 4 USB 2.0 ports, a single HDMI port, VGA port and audio in ports. The USB 2.0 ports should be sufficient for connecting the included Dell wired mouse and Dell wired keyboard. Additionally, should you need to connect an external monitor, you can opt for the VGA or for better image and video quality, HDMI port.
All in all, even while the Dell Inspiron 3668 i3 is an entry PC, Dell didn’t make that many a compromises on the port section as we expected. While we would have appreciated a USB 3.1 port, better yet a USB Type-C port, for the price I think Dell did okay. You should be able to find better port systems with a wider selection of ports on other higher-end desktop PCs
Other connectivity options available the Bluetooth DW1707 card.
At the current price point that the Dell Inspiron 3668 sells for, you will be hard-pressed finding a PC with all the components and performance of your dreams. That’s because, at the sub-$300 price point, most PCs are entry-level and compact models. Consequently, they have more than a few compromises made to accommodate the low price.
That said, the Dell Inspiron 3668 combines the best of components that should remain functional longer, up to five years at least.
Speaking of components, the Dell Inspiron 3668 i3 packs the 7th Generation Intel i3-7100 Dual Core processor based on Kaby Lake architecture. The card is a predecessor of the Intel Core i3-6300 and builds on a few aspects. I’m looking at video decoder for 4K video technology, improved Speed Shift technology (that dynamically adjusts the CPU clock,) and support to Optane technology (which is a future kind of high-performance SSDs.)
To clarify, that means it can handle some 4K content thrown its way and manage high-end futuristic SSD storage should you ever opt to upgrade in that direction.
Along with that, with a 2.4GHz processing power, lack of Turbo Boost technology and 3MB Cache, the i3-7100U is relatively slower than its Core i5 counterpart (Dell Inspiron 3668 i5 Review). However, that does not necessarily mean bad user experience.
It excels in tasks such as daily computing chores, web browsing, running Office documents, and editing images. Professionals will be happy to note that it also is capable of high-resolution 4K video playback and rendering 1080p 60 fps videos. It is capable of handling such tasks without consuming much power (less compared to previous processors) and generating much heat (also less than predecessor)
Memory and Storage
Still, on performance, the Inspiron 3668 handles itself well in multitasking tasks thanks to two cores and an 8GB DDR4 2400MHz memory. Typically, most entry-level desktops come with 4GB memory but the Dell Inspiron has double that which is excellent for Windows 10 systems and handling performance of its league.
Also, as prevalent on most budget-entry PCs, 1TB HDD storage is the norm when it comes to storage. Our unit sports a 7200RPM HDD which for the most part is sufficient if you’re in the market for plenty of storage for your data files, movies, games and software.
As far as gaming is concerned, there is no dedicated graphics card that comes with this unit. Only an integrated Intel HD Graphics 630 card is available meaning the PC is not capable of running modern triple-A gaming titles. Still, it should, however, run a couple of other low demanding games on medium and low settings if you really want to play.
|Settings and FPS
|Batman Arkham City
|720p, Low settings, 61 fps
|Call of Duty Infinite Warfare
|720p, Low settings, 20 fps
|Dead Rising 3
|720p, Low settings, 24 fps
|Metro 2033 Redux
|720p, Low settings, 31.6 fps

The Inspiron’s Tip of the Spear
One of the most defining aspects of the Dell Inspiron 3668 desktop is pricing. And the Dell Inspiron i3668-3106BLK-PUS definitely offers a great value package at that. But that couldn’t possibly be all. There are others, case, and point, the components. For instance, the modern core i3-7100U processor, 8GB DDR4 memory and 1TB hard drive storage. Those make a name for the Inspiron 3668 and should be impressive at most casual tasks and 4K video playback.
The only wrinkle, yes there is a wrinkle, is the lack of solid-state drive and a more futuristic USB port like the USB Type-C. The SSD is to ensure fast booting up and fast saving and retrieval of data while the USB Type-C ensures fast data transfer way into the future. On other fronts, the case didn’t blow us way either with its subtle no-frills look. But the interior is simple and accessible and supportive of upgrading which kind of cancels that negative out.
Altogether, the Dell Inspiron i3668-3106BLK-PUS manages to get our Editor’s Choice for its modest design, great low price, and performance. Usually, PCs at this price point are basically web browsers. So the Dell Inspiron strides ahead here. All things considered, it should serve you well.
P/S If you’ve got some extra cash to consider upgrading to SSD storage and you’ll be happier with the performance.
