Apple iMac

The 2017 iMac is a fine update to Apple’s desktop computing platform, but suffers from a few nagging design quirks, as well as its own place amid rapidly-evolving desktop design trends. Still, for Mac fans in need of an upgrade, the 21.5-inch model presents surprisingly impressive value. With upgraded internals and a 4K screen employing an impressive color gamut, not to mention high-quality, comfortable input devices, the 2017 iMac is well worth your consideration if shopping for an all-in-one computer. The good news is that this time round both the 21-inch iMac and the 27-inch iMac have received a processor boost to the newer Intel Kaby Lake range. So no more lagging behind for the 21-inch model. 

On to the display. When it updated the iMac , Apple added a 4K Retina display to the 21-inch range. This time round there are two 4K Retina iMacs: a 3GHz quad-core model and a 3.4GHz quad-core model. All the new 21-inch and 27-inch iMacs feature new Intel Kaby Lake processors. The 21in iMac models get Kaby Lake processors running at up to 3.6GHz (which is a build-to-order option). The iMac has stood up pretty well over the years and continues that trend. True, it's no longer a system that you can really get excited about as cutting edge,As we can see, the 3.4GHz Kaby Lake processor in 2017's 3.4GHz 21.5in iMac sees scores of 14,106 and 4,894, while the 2015 21.5in model with 3.1GHz processor scored 12,192 and 4,174. While the newer processor has a faster clock speed, so that will account for some of the difference, it is still a fair leap in power. Intel’s graphics (which are integrated on to the CPU) use the computer’s RAM, while dedicated (or discreet graphics cards have their own memory.  The performance is much improved. Plus it's got two USB-C/Thunderbolt connectors which can drive more external displays and faster file data transfers. 

Dell Precision 5720

           The Dell Precision 5720 is, by and large, a rebranded version of the company’s own XPS 27. Dell's previous all-in-one workstations were mostly limited to Optiplex models, which have the more staid looks you'd expect from a machine destined for reception areas or rows of cubicles. The major differences lie on the inside. Unlike the XPS 27, the Precision 5720 is Independent Software Vendor (ISV) certified to work with pro-grade content and design applications from the likes of Adobe and Autodesk, to name a few. It has all of the supporting hardware, including AMD Radeon Pro WX-series workstation graphics, Intel Xeon server-class processors, and ECC memory. Very few AIOs on the market can claim to offer that kind of hardware. Additionally, as a Precision-branded unit, you get access to Dell’s business service and support, versus the premium (albeit consumer-grade) support on the XPS unit. The desktop was pre-installed with Windows 10 Pro 64 bit operating system. However this was a Non-touch LCD, Dell Workstation AIO with fixed stand.

    There are a dizzying array of drive options on the Precision 5720, offering plenty of combinations for those who need speed, space, or both. They include 500GB or 1TB hard disks, a 1TB hybrid drive, and several SSD-only options that range from 256GB to 1TB and connect either via SATA or M.2 PCIe. You can configure your Precision 5720 with up to 64GB of memory, with or without ECC, and there are four DIMM slots to hold it. My review unit comes with 32GB of memory, a 512GB SSD, and two 1TB hard disk drives in a RAID 0 array. That configuration results in snappy startup and app loading, since all of the system files are located on the SSD. Dell includes a standard one-year warranty with the Precision 5720, but since this is a business-oriented machine, the company also offers its ProSupport Plus, which includes repairs for accidental damage and hard drive recovery services, as an option.

Aspire S24

Aspire S24 launching the new Predator series and Chromebook 15, the company also revealed its all-new 23.8-inch Aspire S24 all-in-one desktop PC Acer has announced the availability of the Aspire S24, its slimmest all-in-one with the latest 8th generation Intel processors and optional Intel Optane memory. It also comes with a wireless charging base for supported Qi-devices. Acer announced its slimmest all-in-one (AIO) desktop PC — the Aspire S24. The Aspire S24 is just 5.97 mm thick when viewed from the side. The display is virtually borderless and comes with Champagne-gold accents for an elegant look. the all-in-one packs Intel's 8th Generation Core processors with optional Intel Optane memory with Intel Dual Band Wireless-AC technology.

The AIO features a 23.8-inch Full HD IPS display and is powered by the latest 8th generation Intel Core processors. The display can be tilted between -5 to 30 degrees and features Acer ExaColor for accurate color reproduction along with BluelightShield and Flickerless technologies to reduce eye fatigue. Despite the slim form factor, the PC features a 2.1 channel speaker system enhanced by Dolby Audio Premium and Acer TrueHarmony. An Intel Dual-Band Wireless-AC adapter (802.11ac 2x2 MIMO) enables reliable wireless networking. The AIO boasts of fairly generous storage with up to 256 GB SSD and 2 TB of HDD space. It can also be configured with optional Intel Optane memory for even better storage performance. It comes preloaded with Windows 10 and also sports a wireless charging base for Qi-enabled devices.

we need more than a strict diet and a workout regimen to be this thin. Acer has worked its magic on the Aspire S24 all-in-one, sending it off to fat camp and not coming to collect until it achieved a barely-there 5.97mm side profile. A 90% screen to body ratio means your eyes will be instantly drawn to one of the most beautiful desktops we've ever seen. As much as you would like to just stare at it, though, it's still a desktop - not a piece of modern art.
