Neighbour had a '4 year old' laptop and asked if I could put Win7 on that thing. Said that wouldn't go down all too well since it's a 1.6GHz single core Celeron M chip with 1GB of RAM (Win7 requires 2 minimum).
Installation didn't go smoothly at all and it kept freezing. After finally booting the the PC froze on the desktop and it took literally well over 10 minutes to go to Google using IE8.
Tried to install XP back on it but the PC didn't even recognize the install CD, not even after formatting the Win7 drive so I had to re-install Windows 7.
Then got the brilliant idea to install Elementary OS on there which only asks for .5GB RAM, but that didn't even support the CPU, which isn't even 32bit apparenty.
