So you want to buy some shuttle K45's? Good for you. What do you want? This forum is for questions. If you're looking for some, I'd suggest Googling it. You may also wish to make a post on Craigslist about it. I just looked up that particular model, and I'm going to go ahead and suggest that you not buy them. Seriously, ATA-100 HDD's? They have all old, last generation, inferior hardware.
For what purpose do your need these machines? Depending on the purpose, we can suggest a different machine or give you specs for one. (We'll need a price point as well)
