Earlier on, I was in a small 'local' computer store with my aunt and cousin, my cousin got a new laptop but the wifi was ****ed and they went to replace the wifi card. In the waiting area they had a huge palette of refurbished Pentium 4-era IBM Thinkcentres... there were some that used a really small chasis with a proprietary motherboard and others were a desktop chassis with what looked like a mATX motherboard.
So there I was, looking at it, wondering if it was in fact mATX or not, and my curiosity got the better of me. None of the store employees were around, so noticing the case open buttons, I pressed down on them and opened up the case. It was in fact a mATX case. The fun happened when the lid had to go on... It was one of those designs of case where the top part angles into the bottom part and slides in (I've seen the same design on HP and other brand computers). Problem was, no matter how hard I tried, I could not get the thing to go back on properly. After some futile attempts, my relatives were doing some serious face-palming, so I kinda got it about 95% closed and said I'd call it a day. But sitting there, waiting, it kinda annoyed me, so I decided to play around with it a bit more, this time pressing in the case open buttons at the side. This time, I succeeded in getting the thing to slide closed fully, but whatever way I had done it, the buttons were now stuck behind the side of the chassis, which would probably make the case quite hard to open again.
The moral of the story - never let me near old computers.
