That's a hard question to answer not knowing what your going to do with the chiller.
If you cooling a cpu only, I would go with direct die.:)

I second that, if it's a single evap cooling system you're after, then direct die is better.

I'm in process of modding some Mach2's and I've been test running them with pure propane (R290) and with a full charge they're pulling to about -55 on one and -58 on the other (fluke temps) which is as cold as -78 on the display.

I'll have to load test and see what that ends up at, but really there's nothing wrong with a propane single stage. Doesn't have the capacity of 404 or 507, but it doesn't cost nearly as much either.

well I was going to start out just cooling the cpu and eventualy move to my gpu once I gain more knowledge and experience with this.

and what is direct die? I thought it was taking off that cover plate on the cpu exposing the core.

[the_new_guy]

no DD is when is stead of cooling water to cool the cpu you cool the cpu directly with the expanding and evaporating gas

[Comp-Freak]

To add, Direct Die is when the evaporator (the place the liquid refrigerant boils) is on the cpu itself and indeed not cooling for example water.

ahhhhhh then yea i would be doing direct die with my ss, and the chiller would be some mixture of maybe 50 50 antifreeze and water? or whatever the best mixture is.
