The strength of retail shop cases with glass tops

[fcgamer | 5,055]

So I scrounged this retail case from a restaurant next to me, which had gone out of business. It has a glass top. The dimensions are 20 something like 36 * 10, with 35 inches running between the supports; however, the glass also is affixed to a back wall that is about half an inch thick. The glass is about 1/4 inch thick, seems to be tempered but I'm not 100% sure.

I want to throw these plastic storage units on top, with the famicom games inside. Depending how many I use, the weight is going to be between 135-190 pounds.

I guess what I'm wondering is if this is even safe? Will I come in some day to find the glass shattered? Should I think of an alternative? Or can these things support a lot of weight?

Tempered glass will have smoother/more even edges than regular glass.

Here is a site that will calculate load bearing.

If you want to be sure you could insert a piece of wood (not particle board or plywood) on top of the glass - looks like the glass is not going to be visible anyway.  You could also paint the wood to match the side panels on the shelves.
