Hello, I've not seen you for a while!
I was at my parents this morning when I was presented with a computer that I lent my father about 7 years back 'just for a few months', and I'd forgotten all about it!
It's an Athlon XP 2500+ based system on an ASUS A7N8X board with 1.5GB DDR RAM, 1x120GB sata drive with 2x40GB pata drives, an AGP Gigabyte GeForce 6600 (128MB), and a 802.11G PCI wireless card all contained in an EZ Cool Alpine case (the one that looks like a Mac Pro). It was quite well specced in it's time!
I just wish I could fire it up at home but all of my VGA cables are in the office, but the question is, what do I do with it? I do have an old socket 775 motherboard and top spec P4 in the office which could be used in there to make it work a bit faster (I may have an old Core 2 or Core Duo around as well) but it does seem a shame to waste the opportunity to cobble together a few old components to make a new system.
