You don't really need to build your own computers, it doesn't really save money these days, it's not 1998 anymore. Most PCs and Macs work directly out of the box as well. You just need an HD cable to hook them up to an HD TV. As soon as you have the Internet you have access to services like Steam with much cheaper games and greater genre variety.
Also, OSX will update everything you need just like a gaming console does, and more recent versions of Windows should do the same.
Where the advantage lies is in price, but only if you plan on just gaming and only buying a few games. If you're going to buy dozens of games, and take advantage of non-gaming features on your PC/Mac, then the price advantage melts away.
There is one remaining advantage, that's the availability of certain types of games (like motion control games) and other functions that would be unique to a gaming console (like Street Pass). Then there is the industry itself, a lot of gaming companies release games only on gaming consoles. Gaming consoles do not sell very well today though.
I describe myself as a little dose of toxic masculinity.
