Yeah, the quick and dirty way is to mount your entire tower case (with bolts, ducktape, whatever) onto a rackmount slider. 19" is really wide for most tower cases. It will do. Just that if I mount about 4-5 of these, it is just really messy (like downtown Boston after the apocalypse). Silent fans is already the idea. It's a home project all right. So this is why I am here to ask if anyone already have done a lot more than me (just an idea now) and can offer a more tried and tested solution. Or maybe someone know some existing cases out there that I can adapt. Sometimes, I don;t mind spending $200 to make life comfortable (but not $4000 for an Alienware machine). Tower or desktop really make very little difference in this case. It will be placed flat. And chances are, 99% of computers out there are tower anyway. All 5-6 of my old computers around here are towers. I mean I can throw them away ... but wouldn't it be fun to re-use them and learn something? Install Linux, try to setup a mini file server, etc... Or power a big multi-monitor display. There is a software called Synergy that allows us to use 1 mouse and keyboard to move seamlessly between computer screens as if you are using one computer. Yeah, it still needs KVM, but .... way more fun. Anyway look at this: Thermaltake CORE P200 Pedestal case... check out the fans .... I just gotta think what I really need to do to mount it on a rack....
