Sure.. a fixed IP and server OS would be the absolute minimum required. The key to serving, is REDUNDANCY. This ensures AVAILABILITY of your [website in this case]. You'll notice for example, that a "free standing" -- i.e. not rack mounted -- server [tower] will have redundant power supplies (oftentimes hot swappable).. hardware RAID controller[s].. etc. (note: rack mount servers have all that redundant stuff too) So anyway, you'll notice that your garden variety "desktop" PC [architecture] lacks such redundancy. Same with your I-net connection. If it's not multi-homed -- i.e. redundant -- then loss of connectivity through your [single] ISP, will bring your site down. The good news is software. Gnu/Linux, 'BSD, -- even OpenSolaris -- etc. are ideal server operating systems; especially for stand alone home based servers, as they feature highly efficient utilization of system resources, and are available free of charge....
