| CPU
(average cost): |
Intel quad core
(or greaater) processor (or AMD equivalant), nominally 2.4 GHz or more with Intel
chipset
family. Generally seek the Intel 8th and greater generation
processors (e.g. i5-8xxx)in order to run Windows 11 if so
desired. Intel 6th generation processors will probably be OK as
long as Windows 10 is used and supported (e.g.
i5-6xxx). Intel
generations 9 and 10 will generally be found in refurbished computers,
with generations 10, 11, and perhaps 12 will most likely be found in
brand
new computers. (Again, AMD equivalants) |
| Alternate CPU (lower cost): | Intel
1.6Ghz-class processor w/Intel chipset family (built-in video) -
dual core CPU; i3 family, 8th generation or newer. (AMD equivalant) |
| Alternate CPU (higher cost and performance): |
Intel
Core i7 quad+ core, 2.5Hz or greater with
Intel chipset family). Note: hyperthreading adds more 'cores'; latest i5-10xxx shows 12 'cores' (6 cores plus 6 hyperthreading) |
| ** BIOS: | Not
a significant factor any more; generally a UEFI managed load sequence for added security and protections. |
| Memory: | 16 GBytes,
(most desktop systems have 2 or 4 memory slots) Note: Motherboards using dual channel memory capability (most), use 2 memory sticks of the same brand, capacity, and speed rating for optimal performance. |
| Alternate Memory: | 8 GBytes memory; this amount of
memory should suffice for most simple use needs such as Internet browsing and
word processing and even to some degree simple photo editing. |
| USB Ports: |
Various
motherboards / cases have a variety of USB ports - USB 2, USB 3,
USB 3C. Make sure you have sufficient ports for all your planned devices plus extras -
Keyboard, Mouse, Speaker, Printer, UPS status notification, Webcam, external drive, flash sticks |
| Case: | Mini ITX / BTX configuration (or similar) in a small desktop
configuration with possible access to the DVD drive. Some smaller
configurations can exclude the DVD drive and provide an even smaller
configuration. USB
ports get to be the
issue...make sure you have at least 6 with some on the front. One
storage drive would be typical; for Optical - can use slim optical
player
or even an external optical player. Computers typically come in Mini Tower, Desktop, and Micro sizes. Some even come in small squares or on sticks. Most accessible to internals will be on the Tower, Desktop, and to some extent Micro. For the home environment, the Small Form Factor desktop models should suffice for ease of access plus small size. |
| Keyboard: | Standard
Windows layout with 104
Keys, USB
connection (or wireless Bluetooth or 2.4 GHz dongle) |
| Pointing Device: | Optical
mouse with scroll wheel (USB);
touch pad on keyboard. If you have a touch screen, a pen would be
helpful; how functional a touch screen for desktop usage is
questionable from a human dynamics perspective; a touch screen for a
laptop/tablet computing device is almost a necessity. Note: Irrespective of your favorites, pay attention to ergonomics and ease of use. |
| Floppy Disk Drive (FDD): | Not used at all today. But if needed use an external drive and copy everything off the disks now! |
| Main storage Drive (minimum): | Single Drive Systems: Primary storage for most simple systems should be in the range of 250 to 500 Gigabytes. A key factor is how much non-operating system storage is needed - e.g. documents, photographs, music. These items are much more valuable and need storage considerations for backup, retention, and recovery in case of loss. Primary storage is rapidly evolving to solid state drives - SATA SSD or M.2 SSD. More recent motherboard architecture provides for an M.2 slot and storage is available in M.2 formats from 250GB to 2TB, same with 2.5" SATA SSDs. In either case, solid state storage is NOT / NOT archival - sufficient for regular usage, sufficient for several years. Archival storage of valuable data should be on magnetic media. Basic primary storage should be at least 250GB. Network attached storage or an external storage drive can extend available storage space. For higher reliability, network attached storage should use dual disk drives, configure for RAID 1 (mirroring) or better. Cloud storage may also work but consider if it is down for the moment or not reachable. |
| Alt Storage Drive: | SATA 1
TB,
larger drives for lots of storage of pictures suggested as an ADDITIONAL drive and not main storage - recommend using
external disks in case the operating system disk crashes. |
| Alternative Storage: | For multiple computer households, consider storing all data
files on a Network Attached Storage (NAS). This provides for
backup in the event of a workstation failure, but also provides access
from multiple computers / devices. As always mentioned, backup even the NAS
device and keep copies external to the house; and rotate the backups to minimize impacts of any potential loss. |
| Performance and Storage Condiderations: |
Seriously conside the storage / performance goals of your selection of main storage. I recently ran a test on a Dell Optiplex 3050 computer using a 7200 rpm HDD, a 2 1/2" SSD, and an M.2 PCIE SSD. The Dell cold boot sequence includes a 5 second display of the Dell logo to more easily select various boot options. 7200 RPM HDD: 63 seconds to boot to desktop; 93 seconds to finish boot and ready to work 2 1/2/" SSD: 29 seconds to boot to desktop; 54 seconds to finish boot and ready to work M.2 PCIE SSD: 20 seconds to boot to desktop; 39 seconds to finish boot and ready to work Conclusion: Recommend the Operating System and Applications run from an M.2 SSD if available otherwise an internal 2 1/2" SSD. You'll get noticably better system performance. |
| Partition Info: | Single user: Recommend 25% for primary partition for OS and applications. Store all DATA on extended partition (always backup your data) |
| Partition Info: | Multi user: At least 50% of drive for primary OS partition and applications; Store photos, images & common files on extended partition (always backup your data) |
| Optical Disk Drive: | Given a greater tendency to use USB Flash Drives, DVD Reader/Writers are optional. |
| Optional Additional Optical Drive: | DVD Reader
(no write capabilities needed; configuration very suitable for disc
copying) |
| ** Video Board: | Some
motherboards have Video (and Sound) built-in which may be sufficient. If using add-on video, PCI-Express w/256 Megbytes(minimum); Serious Gamers 4 GB minimum. Make sure the video supports DirectX 12 or better. Many desktop computers and mid to high end video cards support multiple monitors. For serious desktop work consider using two monitors and configure the operating system for dual displays. You'll wonder in amazement how you ever got along without the dual displays. |
| Video Display LCD: | 24"
nominal(resolution
is fixed on LCDs) contrast
>400,
brightness >250 nits Even larger needs use 24" or larger. Some alternatives with HDMI include large screen TVs. It appears that most of the newer video displays are using HDMI and Display Port (DP) connections with VGA going away. In some newer desktop computers, the only native video out is Display Port. DVI (either 25 or 25+4) connections look like they are fading away or already gone. If using a device to convert from one output mode to another in order to connect to the Display, pay note to the directional characteristics of the connection. Some only work one-way...from the computer TO the display. Note: If using Windows 10 / 11, a touch screen may help but may not be required - even an "all-in-one" where the computer and display are integrated as a single device. Touch in a desktop environment may be akward due to the distance of the eyes to the screen usually two feet or longer; touch is more viable on a tablet or laptop. |
| Sound Board: | Generally
all motherboards have sound today. Suitable for the average
usageGenerally all motherboards have sound today. Suitable for
the average usage |
| Speakers: | Small is sufficient; generally about $30. |
| Modem: | Digital Subscriber Line (DSL) - uses existing copper
phone lines and provides about 3mb/sec speeds (down). DSL Modem provides external connectivity to phone line and outputs ethernet or is a router with several ports (and usually a wireless network for the house) [Note: DSL requires low pass filters on all telephone instruments other than the DSL modem]. FIOS (Fiber) services use direct to the house fiber connections and an Optical Network Terminating Device (ONT) to provide Internet, telephone, and television services. A WAN/LAN Router is also needed which usually provides wired and wireless LAN capability. Cable- uses cable TV systems for Internet connection and also requires a cable modem, generally to the DOCSIS 3.0 (or above) standard, and has a single ethernet port for direct connection to a single PC or to a router for multiple PCs or wireless. (Note: In many cases you can provide your own company-approved cable modem and save about $150 per year). If you leverage the cable provider for telephone service, a special class of cable modems is required. Cellular Hot Spot - This mechanism uses the cellular phone system and your modern cell phone to create a WiFi hot spot and leverages the data portion of your cell phone account. But you'll need to manage you data plan as some downloads can be quite large. A separate WiFi "puck" may be available...essentially a dedicated cell-phone type device for networking. 4G and 5G cellular service is beginning to offer home Internet via the 4G/5G network. (Note: Firewall (hardware and/or software) required with any Internet use) |

Internet Connectivity (LAN):
|
Fixed Wire:
10/100/1000
mb Ethernet (ports usually on motherboard); use Cat 6 or 6E unshielded
twisted pair wire for new installations. This most likely will provide the fastest connectivity. Wireless: 802.11ac (WiFi 5), b, n, or g - wireless networking; for security, use WPA or greater encryption (WPA2, WPA3), consider not advertising SSID, maybe even access by MAC address only. WiFi 6 and greater is emerging for improved connectivity to the hotspot. Internet Gateway: The Internet provider (ISP) will generally enter the premises/house via a gateway router of some form. Generally a router with a wired and wireless capability. Using this single router is workable, but open to vast security pitfalls. We prefer to have additional routers attached to the Gateway router...in essence a double router, double NAT, double firewall configureation. From this second level of routers, internal WiFi can be used, Guest WiFi can be used. In addition, another second level router (WiFi or wired outputs) can be used for Internet of Things (IOT) and/or entertainment devices, thus separating these devices from the core data. Internet of Things (IoT): New household items are more and more desiring Internet connectivity. It is important to place IoT devices on their own network, unreachable to the core network of the house. Security issues continue to emerge concerning IoT devices and attempts to exploit holes in IoT security to access the core network. The IoT network should have its own strong encryption capabilities. Guest Wireless: As with the IoT devices, it may be a good idea to have a Guest Internet Wireless to provide good hospitality to your guests. This keeps your data and their data separate and protects your core network from any malicious interference. Similarly, the Guest Network should have its own strong encryption capabilities. |
| Operating System: | Windows 10
Home or Pro (64-bit edition for new installations).
Windows Account Configuration I like to make sure that for day-to-day operation and overall system security, using Windows is at the USER level and not the ADMIN level. Therefore every system I configure has both an ADMIN-level account and at least one USER-level account. It is recommended that the first account set up during a Windows installation is ADMIN, I prefer a local account (during installation, do NOT connect to the Internet). Then set up the various USER account(s) which can either be local or with a Microsoft Account. Thus as a minimum, two accounts will exist on the computer. Make sure the Admin account has a password. The purpose of this setup is to make sure that any attempts to install software first ask for ADMIN approval and password...a way to mitigate any possible external threats.

| Alternate Operating System: | A form of Linux (32-bit or 64-bit edition) |
| Green IT: | RoHS specification (no lead); 80 Plus (power supply efficiency better than 80%; EPEAT (Silver minimum); Energy Star 4 or better; Recycle your old computer after cleaning out your data. |

ABOUT NAME
BRANDS
In some cases, use of Name
Brands
(instead of generic brands) is
critical to system
success. This is especially true for the more modern Operating Systems
like Windows and Linux. The drivers
required to operate the
peripheral devices need to be obtained from
a ready source. Some
generic products do not have WEB or
technical support and it may be impossible
to locate the manufacturer. Use of name brands in these cases also
assures drivers are included infuture
editions of modern
OSs. Use of a
"product compatible"
rating will not
suffice! |
