I have an original Pwermac G4 350 MHz (yeah i know, a little behind are'nt I) and i want to remove the zip drive and put in a fan controller, which ones will work with it??!

Any 3.5 inch on should. I don't think you really need one though, there is only one fan in the machine that you can control.

yes, i know, but im adding a couple fans, and im going to add a cold cathode or two, so i might get a light contoller instead or a combo kit with fans and lights controllers.

I see. With fans, unless you are overclocking, or Your putting a CPU upgrade in, the stock fan should do fine. I have a Dual 550mhz G4 with 2 hard drives, 768megs of ram, and a Geforce 4 titanium,and all it has is the stock fans (and the one built onto the video card. The CPU fan in it is stock, and only turns on if it gets tooo hot-which hasn't happened yet. The power supply fan is always on, and that takes air out of the machine pretty well, and the 120mm fan on the side of the case keeps everythiogn else relativly cool. I am telling you, do not add noisy fans unless you have to. As for the lighting- if you do a clear side panel mod (look around its in a mod guide here) maybe I would suggest it. Those old G4 towers are very solid workhorses and need very little work on top of stock. If you want to do this anyway-take my advice with a grain of salt, it's just my opinion.

thnaks, that is great advice. I am planning on putting a new processor in, a cheap 1 GHz because i need to run virtual PC (gasp), i am inthe process of clearing the panels, but am not finished yet, so thanks.

I had no touble hooking up an "aerogate" fan controller (and temperature reader) to my quicksilver I can't imagine it would give you nay trouble.

Any fan controller will work as long as it doesnt connect to the motherboard for temps and
such. I use pci fan controllers so the front stays stock. A full drive fan wont fit because a
zip is smaller than a full size drive. But the you can "mod" it to fit which is cooler anyway.

There is a good use for the fan controller. It forces the fan to run at 12volts instead of 5 volts (depending on what type on controller you get) and you have a choice to speed it up or slow it down. Works great if the room the system is in gets a bit warm then what is normaly is. Heres the neat part you can probly add a cat tube light and use the fan controller to act as a dim switch.
