I know this is not going to be a good environment for a computer but I want to setup a low-end system using mostly parts I already have on hand to put a computer in my garage. Nothing important will be on it. Maybe some PDF files of some service manuals I have for my rolling junk. Internet access will be through my wireless router and I might do some music streaming as well. How heat resistant would a standard computer be? I'm considering just mounting the motherboard on the wall, actually and ditching the case all together. I can't remember for sure what the system specs are but I think it's like a 1.2 GHz P3 with 1 GB RAM and a low end video card. I have several old hard drives I can throw at this system as well. I have junk monitors, mice and keyboards as well. I'm thinking about running Presto or some other instant-on Linux OS on it. Come to think of it, the ideal setup would probably be a flash drive holding the OS and no hard drive at all... Any other ideas or suggestions?
