I needed to open up the case of an ipex s300 PC (to replace a faulty CD drive).

At first glance, it looks like I need to undo 2 Allen key screws, and it will pop open… but no, the case won’t budge.

I try a few different angles, a bit of leverage, but nothing would loosen the case cover. After some careful scrutiny, I eventually found out how to open an ipex s300 case:

• don’t undo the front allen bolts.
• by looking very carefully at the back, there are 1 (or 2) screws. The screws are very close to the top of the case, so they are easy to miss, as there is a slight metal lip, just above them.
• By undoing these screws, the top cover can be easily slid forward (towards the front of the case.
• Remember to be careful while working inside a PC… you can easily damage components.
