Is this the same as the A500? .. if so what it is is one of the best built cases on the planet with a slide out tray and rolled edges and is made of of heavy grade steel.
It was designed in the Klamath days with a PSU with fully vented underneath so that heat from the vertically mounted Slot-1 CPU was sucked out so NO exhaust fan - I do NOT recommend this case for use with an Athlon or Duron as you will have two fans pulling in opposite directions, also the HS/Fan being half under the PSU means that you`re restricted for space , it gets by with a CuMine or Tualatin system because they run cool in anycase..
Real shame, I had to buy a new case as I had terrible temps despite all sorts of makeshift exhaust fan bodges to try and get a good airflow..
As I said that was the A500 which was still available up to 3 months ago at least, if InWin have made an Athlon friendly case of the same build (V500?) it will be both expensive and of blisteringly high quality..
