Just because you bought a new PC doesn’t mean you must throw away the old one. Here are some tips to make the most of an older computer.

Icy Box Nas Media Server - Komplett.ie
Convert it into a server
If you have a home network with family members on it, reusing the PC as a NAS (network-attached storage) box or even as an actual server may be just the ticket. However, it’s not simply a matter of plugging an old PC into a network connection. Most desktop systems aren’t configured to be effective servers or storage systems. For one thing, they probably use too much power. You’ll want to set BIOS power management to run cooling fans in quiet mode, if that option exists. You’ll also need to set up the operating system so it doesn’t shut down at inconvenient times, yet runs in a low-power state when not being actively used. Bear in mind that you’ll probably want to run your server ‘headless’ (that is, without a monitor), and sans keyboard and mouse as well.
While you’ll require a display and input devices for initial setup, make sure that the reused system will work properly without them, Also, the operating system is likely not well suited for storage applications, particularly for multiple users. Windows XP, Vista, or Windows 7 can function well as a storage repository for a couple of users, but you’ll want to create user accounts for each person who might need access. You may also want to set storage quotas. A better solution: Install a proper network operating system. Once choice is Windows Home Server. However, it costs €90 and may prefer newer hardware.
An alternative is FreeNAS. Open source software, FreeNAS (
http://freenas.org) is designed to turn a PC into a network-attached storage device ad is based on FreeBSD, a Unix variant. If you’re not certain you want to commit to an unfamiliar OS, you can download FreeNAS as a LiveCD version; this is an ISO file that, when burned to a CD, will boot off an optical drive and run from memory. You can keep your old OS on the hard drive until you determine whether FreeNAS fits your needs.
Make it a secondary computing server
Not a widely regarded option but if you’re a content creator using applications like 3Ds max, Adobe After Effects, Sony Vegas, or AutoCAD, having another PC to help with distributed rendering can greatly speed up final renders for complex projects.
Each application handles distributed rendering a little differently, so you’ll need to consult your documentation. Typically you’ll install a lightweight application on the secondary rendering system, which will take data and commands from the primary system and then return results when done. The main application on your production system, or a separate manager app, manages the rendering across multiple networked systems.

Ubuntu - Viable alternative to Windows
Turn it into an experimental box
You’ve probably heard about this Linux thing, and maybe you’d like to give it a whirl. But the thought of trying to create a dual-boot system on your primary PC leaves you a little green around the gills. Now you can experiment to your hearts content on your old box. Check out Ubuntu (www.ubuntu.com), the sexy Linux distribution that geeks love to, well, love. The neat thing about Linux is all the built-in support for older hardware, so installation is usually easy – in fact, installing Ubuntu is sometimes simpler than installing Windows. And a wealth of free software for Linux is just waiting to be tried out. A number of true Unix-based operating systems are available, ranging from FreeBSD or PC-BSD (based on the Berkeley Unix version) to OpenSolaris, based on the Sun Microsystems version of Unix.

Home Theatre PC
Set up a HTPC
Media streamers are fantastic pieces of kit. They allow you to send all of the TV and movies that you have stored on your PC or NAS box, straight over your home network onto the TV in your living room. While plugging a media streamer is relatively straight forward, configuring it to work with your home entertainment system can be a bit tricky.
With a Home Theatre PC (HTPC) or Media Center appliance you have -
a convergence device that combines some or all of the capabilities of a personal computer with a software application that supports video, photo, and music playback, and sometimes digital video recorder and time shifting functionality.
In order to set up your HTPC you’ll need a TV Tuner card – Hauppauge and ATI are recognized manufacturers. You might also want to take a look at things like memory (although almost any DDR memory is suitable for up to two TV tuners). Depending on where you plan to keep the system you might additionally look at the casing and ensuring that you’re providing sufficient cooling.
