My schools are always breaking down, even the brand new Lams we got. Of course, they are in the kind of case that is 2.5 inchs wide and stand on the side (Its a desktop PC with a stand so it vertical like a normal tower case. It makes the CD-ROMS (which have horrible tabs for keeping the CD in). They have a fan on the top, side, and back, and our students feel the need to punch in the grills and break the fans. And then the heating problems come around... you can actually visbly see the system slow down compared to one of the computers with function fans. I estimate one lab has about $200 dollars in fan damage (10 computers with 2 fans out each, with $10 fans including shipping). Thank god I'm out of there.
But yah, you really cant use schools as examples, as no one treats PC with any type of respect. The teachers dont know how to use them, and the students are just plan stupid sometimes.
Thank god I'm out. ^_^
