Design and Features

We’ve seen other Dell gaming products and can attest that the Dell did not go all out with uncertain gaming audacity on the Dell Inspiron i3668 Desktop design. The case is a standard metallic one shrouded in a plastic shell, but with a unique style to it that mostly represents a toned down design. Despite being a Dell product, it sits far away from the Alienware lineup in terms of aesthetics.

The side panels are not fluxed with grilles and vents as is with the spruced up Dell Inspiron 5675. In fact, our unit is not as elegant as other sub-$1000 desktops with tempered glass side panels (CyberPowerPc and iBuyPower). No, the side panels are metallic, easy to open and we loved them for having their own touch of originality. Generally, the build quality speaks positively about prebuilt desktops from big manufacturers like Dell.

The Dell Inspiron i3668 tower measures 11.9 x 6.1 x 13.9 inches which make is slightly smaller than both the iBUYPOWER 9200 Gaming PC Desktop (25 x 12.5 x 21.38 inches) and the CYBERPOWERPC Gamer Xtreme VR GXiVR8060A5 Gaming PC (18.46 x 7.87 x 17.89 inches). However, even with the chic and understated look, its sheer size is a testament to easy expandability and upgradability down the road should you ever need. It’s a welcome sense of scalability every gamer looks forward in a gaming rig.

The side panels are clean and simply designed with serious cues taken from professional desktops. To get to the gut there are four screws you have to go through. It’s pretty easy to get in if you’re good with a screwdriver.

Port land

The Front side has a couple of ports too

Apart from cool design and high-end components, the other best thing about the Dell Inspiron i3668 desktop is that it has oodles of ports. The front has two USB 3.0 ports, Audio port, a card reader (supports SD, SDHC, SDHC, MMC, MMC+) and an Optical drive DVD+RW. The rear has a list of other ports including a single VGA port & HDMI port, and four USB 2.0 ports for your mouse and keyboard connection. You also get additional connectivity options like 802.11bgn Wireless and Wired Network Connectivity and Bluetooth 4.0. Upgrading to a dedicated graphics card is the best alternative to getting some extra sets of futuristic ports for external connectivity.


There are many configurations of the Dell Inspiron i3668, but our unit was among the highest on configurations on the list. Thankfully, when it comes to everyday performance, our unit is a beast. It juggles through daily run-to-the-mill tasks efficiently. That includes Windows, web browsers, programs, and software rarely leaving us wanting or waiting. Thanks to a brilliant assembly of components the Dell Inspiron i3668 can go toe-to-toe with other premium desktops in its space.

Under the hood of this baby is an excellent processor, sizable RAM plenty of storage space and motherboard. Right at the heart and center of it all is the processor; the Intel Core i7-7700K. The Intel Core i7-7700K was Intel’s new processor in 2017 (codenamed “Kaby Lake”) made with high clock speeds and overclocking capabilities. It’s a great chip made for those looking to handle challenging tasks such as photo editing, video editing, 3D work, and gaming.

Also, this quad-core processor loads at a base clock speed of 4.2GHz and since its an unlocked CPU, it allows overlocking for better speeds of up to 4.5GHz. On benchmark tests, it scored an Average CPU Mark of 10783 which compared to Intel Core i7-8700K’s 16,009 is a fairly impressive score.


Moving on, there’s also a 32GB DDR4 memory and plenty of storage (2TB mechanical drive and 256GB Solid state drive). The 2TB hard drive storage is pretty sweet especially if you’re looking on storing large files and folders on a long-term basis. But the solid state drive is much better storage option albeit its market prices. For this PC, the operating system (Windows 10 Pro) is loaded on the SSD. It helps improve performance, boot times and loading of software such that you won’t have to wait beyond averagely 20 seconds.

Gaming Performance

So far, the Dell Inspiron i3668 Desktop brags of the best in industry components sufficient for gaming and intensive workloads. However, it’s one main caveat is lack of dedicated graphics card, a concept that might not sit well with many buyers. On the bright side though, if you’ve got any skills on building a PC, this should be a piece of cake. The Dell Inspiron i3668 case has an evolved interior that allows for addition, switching and upgrading of components.

You can opt for a dedicated graphics card such as the Nvidia GeForce GTX 1070 or higher 1080. Either card should ensure the rig runs beautifully with no noticeable frame drops, latency problems, and crisply textured gameplay. Of course, after the upgrade, the rig will have cost you more than expected but you can rest assured it will be among the premium gaming category.

The one caveat you might have to deal with is upgrading to a dedicated graphics card to something like the Nvidia GeForce GTX 1070 or higher. That way it can handle intensive AAA gaming.
