Need some Erector Set advice

[RichMayo]

I've wanted to build a custom case for a while now. I've done some model building and I've learned a few things (like my model-building skills are weak, weak, weak....)

 

So instead of carpentry, I want to try something a little less easily screwed up. Something along the lines of a grown-up erector set....

 

 

Can anybody recommend any sort of commercial product I can use to accurately build a 16" cube box? I read a mention once of somebody using parts from a modular closet system set, but I haven't been able to get more info.

 

I would even be willing to use wooden shelf system boxes, but I haven't been able to find anything in the right size.

 

 

Has anybody got any suggestions at all??

 

 

 

 

Thanks,

R.
