Tryten Keyed Case Lock

[Dot Matrix]

Anyone here use any kind of security bolts for their case? I've been searching around for something to lock my Antec 900, and I found these keyed case locks from Tryten an wanted to ask if they're worth purchasing. I'm rather upset the Antec never came with a way to lock the case shut for how much hardware can fit into it. 

 

Thanks.
