Which is better overall, buying pre-built or building your own? Which is more cost effective? Granted that I know how to build a computer, which would be more reliable of a system? Basically, I want a new computer for, a slightly intensive education program (I have my schoolwork on CD-ROM, well some of it), lots of basically everything you'd do on internet (my business is online), some gaming (not too intensive though, nothing too 3D, some photo editing and quite a bit of entertainment stuff (movies, music, etc.). for those purposes which would be a better computer for me to get, prebuilt or to build my own? thanks.
