I guess this is the best place to ask.
I'm looking to set up a permanent "server." Realistically, I want to be able to just use it for hosting one or two games/applications, like Minecraft, Mumble, etc., etc., There would always be less than 5 people so it shouldn't be too intensive. If I could use the HDD as a backup for a few GB's of critical data, cool.
Would something like this be a good candidate for inexpensive, potent, with the added bonus of being unobtrusive and small? http://www.zotacusa.com/zbox-giga-id72-plus.html
