In an effort to get some serious control over his home theatre PC, DIYer Jarolix skipped the remote ad went straight for a fully featured desktop computer built into the coffee table.
You can always control your media with a regular remote, or with a myriad of iPhone and Android apps, but few things give you as much control as a full desktop program. Jarolix, looking to control Spotify and XBMC on his TV, bought himself another computer monitor, added a touchscreen, and built the whole thing into his coffee table for easy access. You could, of course, simplify the build a lot by buying a touchscreen monitor or tablet instead of modding a regular monitor as well. Of course, you'll need to cut some pretty big holes in your coffee table, so I wouldn't do this on your grandma's antique heirloom, though a cheap LACK table from IKEA (like the one Jarolix used) is probably perfect.
