Electronics enclosures are extremely important when it comes to protecting electronic equipment. And while they may not seem very different from one another, there are a number of differences that can drastically affect their performance. Also, the manufacturers of enclosure systems may seem similar, yet there are differences in what a company can offer.
When it comes to buying an enclosure, there are a number of key points that can improve purchasing decisions. Overall, strength and rigidity are two of the most important qualities to look for in an electronic enclosure. But once those qualities have been established there are a number of other features to consider, such as expandability and design flexibility.
In terms of strength, a fully welded frame will be more stable and provide better security than a bolt-together frame. Welded frames may seem more expensive, but the cost and time used in assembly will offset that extra cost up front. If a welded frame is not available, some companies offer pre-assembled enclosures that arrive together and ready to use.
Another important quality to keep in mind is thermal requirements. Computer equipment is getting more powerful, and therefore generates more heat. An enclosure system that can dissipate heat effectively is critical. If the environment is dirty or dusty, the enclosure must also be able to filter the air used to keep equipment cool as well. Examine thermal demands of the area thoroughly before making a purchase.
When it comes to setting up an enclosure, no two set-ups will be exactly the same. When ordering an enclosure system, be sure to check out configure-to-order options and color choices. If trying to match existing units, color can be important, and not all suppliers offer more than one or two colors. The ability to custom-configure an enclosure is important. Some companies can offer unique enclosures that meet the needs of a specific situation. When ordering a custom enclosure, insist on in-house design and manufacturing from the supplier. Some companies rely on others for these services, but for successful customization, in-house design and manufacturing is a must. These services assure continuity, accuracy, and overall quality for the project. Knowing that the supplier offers these services will also help when future customization projects arise.
Research a supplier’s manufacturing capabilities and ability to deal with demand surges so that orders will not be late or out of spec because of the scope of the project. Products made overseas are at risk for delays from logistics, so insisting on products made in America will insure quality and more reliable shipping times. Using a “closer to home” supplier will also make receiving a prototype unit easier. The supplier should be able to produce a quality prototype quickly for time sensitive design projects.
International Organization for Standardization (ISO) certification will also help ensure that the manufacturer has a quality system that can support production of the highest quality product. In order to become ISO certified, companies must go through a strict testing and certification process. Not all companies are certified to the highest level, so be sure to research the companies that are available. In addition to ISO certification, not all suppliers provide expertise with special need product types, such as Seismic, EMI, RFI, NEMA, or others.
As a general rule, always be sure to check up on the company that the enclosure is coming from. Check the supplier’s financial strength, reputation, years in business, and look at the other companies they serve. Quality suppliers will usually offer a list of references for potential customers.
In terms of delivery, a quality company should be able to provide documentation of delivery statistics, such as their percentage of on-time deliveries. A supplier that uses its own delivery trucks and drivers is also a sign of quality. These drivers are usually specially trained to handle the equipment being transported, and since they work for the company, have greater incentives for delivering an item undamaged.
Buying an electronic enclosure system can seem overwhelming when considering the number of features. But educating yourself and referring to a few guidelines can help you find a quality enclosure supplier that can meet current needs, and the needs of any project to arise in the future.

How To Select The Best Student Laptops
Laptops are the perfect educational tool for students. They can handle an innumerable amount of tasks and serve many different functions that allow students to consolidate all of their class assignments and home studies into one convenient location, which simplifies workflow and increases productivity.
The two most important things to look for in a student laptop are portability and battery life. This laptop will likely be carried in a backpack or shoulder bag from class to class, so you will definitely want a system that is light and easy to transport. There is also no guarantee that you will have access to an auxiliary power supply in your classroom or on campus, so you will most likely want a battery that lasts up to several hours per charge.
Desktop real estate can be limited in your class, so you want to make sure your laptop is compact and economical in size, preferably around 14" X 10" in general dimensions.
As far as individual specifications, you can get by with most base configurations. A 1.66GHz processor, 512MB of RAM, a 40GB hard drive, and a standard DVD/CDRW drive should suffice, but you may wish to upgrade certain components depending on whether or not you want to use your notebook for any extra curricular activities, such as gaming or multimedia production.
Unless you intend to do higher-level networking, or unless your school requires domain-based authentication to access the school network (check with your IT department), Windows XP Home Edition should more than meet your needs for an Operating System.
Lastly, you will need some office suite software to process and edit your reports and class assignments. Microsoft Office Basic will be able to handle most of your needs, however, if you plan on doing any slide-show presentations or website creation, you will want to go with Office Pro.
These are the main things you need to know and consider before purchasing a student laptop. This is just a general outline. Feel free to make additional customizations if you have specific requirements for school.
Please, check out these recommendations for the best notebook computers for students.

Konica Minolta Magicolor 5570 review and Cartridge choice
The 5570 is the latest colour laser to join the established magicolor family. With a quoted top speed of 35ppm for mono and 30ppm for colour, it looks capable of satisfying high-volume workgroup printing and uses Konica Minolta's Simitri HD polymerised toner technology, which claims to deliver superior print quality.
Simitri HD uses toner particles that are uniform in shape, and Konica Minolta claims this allows the printer to deliver finer detail and use less toner than the competition. It also claims the toner melts at much lower temperatures, allowing the printer to save up to 15% on power consumption and reducing paper curling. Plus, it emits 40% less CO2 than conventional toner.
We have no arguments with build quality, and despite being only slightly larger than Lexmark's C532dn the 5570 weighs a hefty 44kg fully loaded. Standard paper handling is spread across a 500-sheet base tray and 100-sheet motorised MP tray, and you can add two more 500-sheet base trays. Along with a decent processor, the printer sports 256MB of memory, and an extra 512MB costs £190 which is very reasonable.
As is the norm nowadays, the printer comes supplied with low volume starter cartridges, in this case 6,000 page yield cartridges which give a cost per page of 7.1p for colour and 1.3p for mono output.
As soon as these are depleted they should be replaced with high yield 12,000 page cartridges and this will reduce the cost per page to a more respectable 5.8p for colour and 1.1p for mono. Another 0.1 p per page can be shaved from these costs by ordering all colours together in the form of the Toner Value Pack. As yet there are no compatible cartridges available, but when they are introduced further running cost savings will be able to be made.
And so to print quality, and it's here the 5570 and its Simitri HD toner scores, as output is far superior to many competing printers. The printer produced some of the best text quality we've seen, with razor-sharp standard font sizes and even the smallest point sizes boldly produced with no discernable smudging. Mono photos don't suffer from any colour cast, and the levels of detail are very good. Colour photos revealed a lot of detail but suffered from slight banding in large areas of a single colour - something the HP Laserjet CP4005n didn't have a problem with. However, if it hadn't been for the banding, we'd have had a tough time telling them apart, as both delivered a vibrancy in our test photos that's often lacking in colour lasers. The quoted mono print speeds are slightly optimistic, as we clocked a 35-page basic Word document at 1min 8secs for an average of 31ppm. However, colour printing was on the money, with our 24-page DTP document completed in 48 seconds for a tidy 30ppm.
The magicolor 5570 may not be able to offer the same output quality as HP's Laserjets, but it certainly matches them in terms of value and speed. The printer is well built, and its low printing costs should put it on any enterprise's printing short list.
All in all a solid colour workhorse that delivers good speed and quality colour printing with moderate running costs should let this one onto your shortlist.
