The listing, HP Pavilion XE748 has ended.
This is a used computer. It originally came with a lousy 64MB of ram and a 700MHz Celeron CPU. I have upgraded the ram to 384MB (It will take up to 512.) and the CPU to a PIII at 733. The CPU currently registers as a PIII at 550. It will register at full speed with the addition of a manual jumper on the MB between contacts. In the meantime it still runs faster than the original Celeron.
The original OS was Windows ME, probably the single worst OS MS ever released. Given that this PC is outdated for any real windows work the OS has been replaced with MacPup Linux. It is a very easy to use OS and as the name implies has an interface that looks like a Mac. Simple point and click GUI on par with that and Windows. Works perfectly and is very small and fast so the pairing with this older PC is good. Boots in less than 30 seconds. OS is freeware and gives you easy access to Linux freeware that will do anything you want. There is software that will take the place of anything you would do on a modern Windows PC.
System has the stock Hard drive and CD-RW with built in sound, video, and a LAN card with room for expansion if needed (Like a larger video card.). Any questions feel free to ask.
