Please don't throw away ugly old faded cases! They can be brought back to look like new.
In this short video I restore a very poor retro ATX case, bought for very little off eBay. Originally made in the late 90's, it had badly yellowed plastic parts and the painted metal cover was also pretty tired.
It is easy and cheap to repair something like this if you know what to do.
I hope this video helps you restore your own computer cases back to their original glory!
