And so when you see a deal which offers both as a 'bundle' (usually at a discount), this seems like a good deal. However unfortunately there can be some disadvantages to doing this. This is due to the unfortunate fact that some cases have a low build quality (which in-turn can make it harder when it comes to building your computer). And the same can be true of PSUs - some are of a low quality too, and a poor quality power supply unit can be harmful to your computer in a worst case scenario and inefficient with its power usage in a best case. Hence when looking for a computer case and a power supply unit, be sure to remember the following tips to avoid potentially getting a 'deal' with a low quality case and a low quality PSU which could end up costing you more in the long run. Seek Out Quality The truth is that quality producers of cases and PSUs tend to sell the two separately. Hence whilst this isn't always true, it's usually true that a case and PSU 'bundle' is one that comes with two relatively low quality components which (as above) will probably end up costing you more in the long run (due to inefficient power usage, poor case quality making your computer building and upgrading more difficult, and more). In general, lower quality cases and PSUs are typically unbranded ones - so if you see (for example) a "600W Power Supply Unit" instead of (for example) "Corsair 650W PSU" or "Antec 600W PSU" advertised, consider avoiding it even if it's part of a 'cheaper' bundle. When it comes to a case and especially a PSU, 'cheaper' isn't always worth it. In other words, if you see a generic PSU or case advertised instead of a branded one from a reputable company (such as from Corsair, Antec,
Cooler master, Chief Tec, Akasa, Enermax, Lion Li or other reputable case and/or PSU manufacturers), consider avoiding the case and/or PSU.Naturally though, if you see a bundle which comes with a case and PSU which are both from reputable companies, this could be a great deal so be sure to consider it!Sometimes, PC cases with power supply units can be a great deal (especially if - as above - both the case and PSU are from reputable companies).
However be sure to make the choice which is right for you, even if you have to spend more and buy the case and PSU separately. We say this because a case and PSU are typically components which you will keep and use for many years. Even if you upgrade loads of the hardware parts inside your system, it's common to keep the same case and PSU.However if you know what case and PSU you want and are happy with your choice, don't spend more than you need to on a higher-priced bundle.
As a result, if you know which case and PSU - or even the general type of case and PSU - you want, aim to get these, and not get a bundle which potentially offers a case and PSU you don't want to purchase. So even if you could save some money, it's usually best to get the case and PSU you want and not potentially 'settle' for less with a case & PSU bundle.It simply means that - once you know what case and/or PSU you want - don't be tempted into buying a more expensive case and PSU bundle.
The most common type of standoff is a brass hex-shaped standoff screw and it can be installed using a hex driver tool, although they are usually relatively easy to screw in using your hands. Another type of standoff is one with a clip style that snaps into the case's tray.
Standoff screws are necessary because the motherboard couldn't simply be screwed directly into the computer case (this is because the case is metal, and if the motherboard touched this metal case it would cause a short-circuit and possibly damage some of the computer's components).
Hence standoffs are used to create a buffer between the case and the motherboard, and thus allowing for the motherboard to be inserted into the case in a safe way.The image below shows the two standoffs described above. The brass standoff screw (left) is fairly common, although the clip-style one (right) is still used - albeit less commonly - today: The two main types of motherboard standoff screws
Installing Motherboard Standoffs The brass motherboard standoffs (or the clip-style ones) are screwed into the computer's case in a way that lines up with the motherboard. You can determine where these holes are by looking at the motherboard - it will have holes in particular places (please note that the four holes around the CPU socket are not applicable; these are to install the CPU heat sink/cooler). Using this as a reference, determine where the standoff screws need to be placed in the computer case.Screw or clip the standoffs into the case's tray.
Once this is complete, carefully lower the motherboard into the case and insert it through the standoffs, being careful not to touch the case with the motherboard.Once this is complete, use the actual (non-standoff) screws provided to screw the motherboard into the standoffs. Do this gently since you do not want to damage the motherboard.This is pretty much all that is required to install the motherboard standoffs and hence the motherboard into the computer case.A computer's software is a program (or a collection of programs) that provide instructions which tell a computer what to do. Computer software can provide just one task, or multiple tasks.
For example, a software program designed to edit photos has one main task (example is photo editing); Naturally though, it'd also have numerous sub-tasks (for example, color correction, cropping an image and red eye removal).Conversely, an operating system (the complex piece of software which essentially runs the entire computer system) would have multiple main tasks such as handling user input and output, managingthe computer's hardware (the components which power a computer), memory allocation and a lot more.
Software programs can be put into two main groups: application software and systems software. Software which allows one main task to be carried out (for example, a program designed to edit photos, as in the above example) would be application software, whereas systems software refers to complex, multi-task programs which help run the system: such as an operating system.
These two main types of computer software programs are explained in more detail below: Application Software Screenshot of a popular browser, internet explorer Internet Explorer 8, a website browser - a type of application software Application software is installed on an operating system (see "Systems Software" below). And as mentioned above, application software tends to perform one main task. A good example of application software would be a website browser; this is the program you are using right now to access this website (for example, Internet Explorer, Firefox, Google Chrome,). A browser's main task is to allow you to surf the internet. Other popular types of application software - with specific examples - can be found below: Word Processing, for example Open Office or Microsoft Office Word allows you to type up documents and letters.
Antivirus Software (for example, AVG, Kaspersky Anti-Virus or Norton Anti-Virus) - Helps protect your computer system against malicious programs called viruses Photo Editing (for example, Corel Paint Shop, Adobe Photoshop or Paint.net) - Can be used to edit photos and other digital images Screenshot of a popular operating system called Windows 7 Microsoft Windows 7 - an operating system which is the main type of systems software Systems software is at the very core of any computer system. Without it, a computer couldn't really function properly. Roughly speaking, systems software manages all aspects of a computer system. The main example of systems software is the operating system - the software that your computer loads up when you switch it on, and which all application software is installed upon. Examples include Microsoft Windows (XP, Vista, 7, and so on), Apple Mac OS X and Linux.
Device Drivers are pieces of software which allow hardware components to function correctly inside the system. They mainly operate 'in the background' hence it's likely that an average user wouldn't have any contact with the drivers themselves. Utilities also called 'Utility tools' are tools which help check, analyze, monitor and maintain different parts of the computer. They usually come pre-installed with an operating system. An example would be 'Disk Defragment' or 'Disk Cleanup' on Windows-based systems. As the following list shows, this category has various topics relating to software programs, such as information about the best antivirus software (antivirus protection is critical to your computer's health and safety), photo editing software and more to be installed/put into the computer's case.
