You can turn your old Power Mac G5 into a grill for the geekiest BBQ ever. Pull out its insides and set it alight and you have a gorgeous aluminum BBQ grill.
Power Mac G5 grill
Developers have been slowly ditching support for PowerPC processors ever since Apple made the switch to Intel. So if you still have an old PowerPC Mac lying around, it probably doesn’t get a lot of use. But if it’s a Power Mac G5, then there is one way you could put it to work as a DIY BBQ.
Admittedly, it’s not quite as simple as just gutting your old Mac gorgeous cheese-grater case. The aluminum case will require a little bit of modding, and you will need some additional aluminum. But, based on a step-by-step guide posted to Imgur, it doesn’t look all that difficult to turn your Power Mac G5 into a serviceable grill.
Once you have your empty Power Mac case, you’ll need to cut open the front to provide easy access to the charcoal that’ll fuel your grill. Then you need to take your scrap aluminum and fit it to the side of the Power Mac case — preferably using hinges so that it’s easy to open up.

Once that’s done, add a wooden base, stick some sand and some coals inside, and then set the whole thing alight. Now all you need is some chicken, some burgers and some sausages.
Presumably, this will work just as well with an old Mac Pro case, too. Check out the guide by clicking the source link below.
