With a gaming PC leave off the case. No more scrapped knuckles. If it is something you tinker with a lot there is no point to it, or get an open "bench test" case. If anyone asks about the pile of stuff and water cooling pipes that is my gaming pc, I just mumble "open computing". If all your artwork is hung not level and not square with the ceiling, and all he furniture not square with the walls and no case on your computer you will find all sorts of annoying people won't bother to visit. Or if they really have to visit they will at least keep their eyes closed.

Micro loans can help the poor, and most of the money comes back to you to lend out again. There is a suggested donation to help with the company overhead and some small percentage of loans fail. But with thousands of loans I've given out over 98% of the loan amounts have come back to my account. I found it helped my geography skills to lookup each country, its economy and cultures. Some of the folks have interesting goals, for example one man in Africa I lent to dreamed of amassing 3 cows and being able to fix the market price of milk in his village.
