I have this Macintosh Mirror Door Drive (MDD) tower computer, sitting on the floor under the table I use as a computer "desk".
About two weeks ago, I had it on my workbench (aka the kitchen countertop) to install a new video card. At the same time, I had to clean out all the dust and crud that had accumulated in it.
This particular Mac model has some prodigious ventilation needs, due to the dual 1.42 Ghz. processors and massive CPU heat sink.
I had to use the vacuum cleaner to get all the dust, etc out of the inside, and you do not want to know about the mat of dust and hair that had been blocking the main air intake for the tower.
Recalling that there had been some attractive aftermarket "riser" legs for this type of Mac tower, I did a bit of Googling and found them!
However, they are no longer manufactured!
So, off to eBay!
And there they were.
Kept an eye on them for a few days, no one was bidding, I placed the minimum bid and waited.
I won them, PayPal-ed the money, and they arrived the other day.
And here they are, installed on my Macintosh:
They'll go a long way towards keeping the dust and whatnot from getting into the computer, as well as keeping that main air intake vent unclogged.
