Right, I appreciate this is a weird one, but I'm trying to find a model of a couple of PC cases I had when I was younger. I am under the impression that they were fairly common, but I can't for the life of me remember what they were called, so I've attempted to draw one in the hopes that someone might recognise what it is I'm after. Maybe it's too generic looking but it's worth a shot:

I remember I had one with the blue bottom as you can see, and one that was exactly the same but silver.

Any ideas would be amazing, I appreciate it might be a long shot though haha.

The case isn't crazy old, probably age it from about 2000-2005.
