This case is not very high quality, but it is a very good deal and very nice if you don't have to open it al too often.
I got a similar case for $40 locally w/o holes, fans and with only 250W P/S. Looks like someone moified this basic case and put in a good P/S. For the extra $7 you get two holes, a decent P/S, and two fans- very good deal, in particular given that it is a bitch to put holes into a case.
For quality cases with good airflow I am using addtronics however they are "mucho denero"
