Again, redundancy. Except for the Mac, most of the pre-built systems are desktop/tower x86 PCs. It's just that it's not something that's standing out as something we really aren't covering at all. Now, maybe a laptop forum, simply because it is a different animal than the standard desktop in that they tend to be noticeably different as far as upgrades and troubleshooting goes. I'm not saying never, but I really don't see enough of a variation with prebuilt desktop/tower systems to warrant it's own separate forum at this point. If we start seeing enough threads often enough, that might be something to look into. Right now, we'll just leave General Hardware as the catchall for stuff not previously covered.
With the jump in forum activity, we'll see how things go as far as a real need. We've got a few things in the works too.
