Owing to developments in technology, computers of very good configurations are available in plenty, and at cheap rates. Given this, it is natural for anyone to discard old computers. But why discard something when it can be of use? Why throw something away just because it is old? And that too when you know it can be of use! Good Uses of Old Computers Personal Entertainment System This is probably considered to be the most common choice of users planning to purchase a new computer. If the PC is in running condition and has a decent hard drive space, you can use it as a personalized entertainment console. You can install software for playing audio files, a DVD drive, a powerful speaker system, and other devices in a typical entertainment system. You can even arrange web access on this system, in case you want to play online radio or watch movies. File Database If you are a user with several computing devices, you can create a file database by using the old system. You simply have to increase the hard drive space of the old computer, establish a wired or wireless connection by using a Network-attached Storage (NAS) device, and start accessing the database through your personal laptop. With this, you can retrieve data when you need it, without having it stored on the hard drive of your new computer. Sell, Recycle or Donate If you do not want to use the old system for any purpose, you can make some money by selling it online. There are many sites that you can use like eBay or Craigslist where you can get good deals. Now this applies to a PC which is in working condition. Selling is one of the uses of an old computer in the sense that you can use it to make some money. Recycling is another way of computer disposal. There are recycling programs whereby you can make money by recycling your old computer. Now, isn't that a use for old computers? Or donate. Yes, donating your old computer to someone in need of it, is a great way of putting it to good use. External Hard Disk In case most parts of your computer have become dysfunctional but the hard drive is still worth using, you can consider using the computer as a means of external storage. You can use your old computer as your 'customized' external hard disk. You will need to spend a few bucks on the USB and adapters though. Trial and Error Another option for using an old computer is to set it up as a 'trial and error' machine. If you do not want to try out various third-party software and hardware on your new laptop, you can certainly use the old system. You can try out different applications, new operating systems, and similar utilities. You can even hand over the system to your children for understanding the basics of computing by installing educational software, typing practice programs, memory games, etc. Television and Video Recorder If the CRT monitor has no display problems, you can use it uniquely.

Using the software that comes along with the TV tuner, you can even record TV shows. This is surely the best way an old CRT monitor can be used. Backup and Occasional Use Your old computer can even serve as a backup in case of emergencies, when you don't have your laptop. Maybe you need to send an important email or create a presentation. Your guests may want to use a computer, which is when you can have them use the old one. In this case though, you will have to ensure that the computer is in working condition, and that it at least performs its basic functions. Video Game Station Instead of giving your system in scrap, it is a good idea to upgrade it and use it as a home gaming console. Instead of loading and playing games on your laptop, you can use your old PC for this kind of entertainment. With just a graphics card and some video and audio drivers, you can start using the gaming system. If possible, have web access ready for enjoying online games. With this you can separate gaming and entertainment from personal data and software you work on. These are believed to be the best ways of using old computers. There are many other creative ways such as using the computer case as a letter box at the gate, an office coffee pot, a resting place for your pet; or simply using the mouse as a toothbrush holder. You can be as creative as your want with using old computer parts.
