i would like to buy similar frame like this one: -snip-

Those pictures look like custom server racks. All you need to do is google mining server racks. They come in various sizes and they give the dimensions so if you want to do DIY you can estimate the size you need.

Even better, you can also try taking a look at Spotswood. They have been building custom computer and mining rig frames for quite some time now and the quality of their work is extremely good. You can visit their website at: http://spotswoodcomputercases.com/
