If all you need is to host a file or directory of files, you can opt to purchase a Network-Attached Storage (NAS). It's basically an external hard disk enclosure with a LAN/ethernet port. You just leave it on the network, independent of any desktop computers. Your data would be available for as long as the NAS and your network is up.

The initial investment is a bit steep (about 10-11k, including the hard disk) but it will save you on electricity costs in the long run, compared to running a desktop PC 24x7.

Below are a few models from the Villman site. I've seen these items on window display in V Mall and Cyberzone. You should hunt around to look for the best bargain. I would recommend though that you stay away from never-heard-of brands if you value reliability.
