Default Will This Enclosure Work For F5/F6?

After custom machining my own case for my F5 I'm looking to take the easy way out on the upcoming F6 and purchase a case. I've found a couple of potential candidates but there's always the question of heatsink size. The first is from SiliconRay.

RE4015 400 x 150 x 373 Aluminum Enclosure - Boards | Kits | Components | Modules | Tools

Nice well ventilated case. I'm waiting to hear back on exact heatsink dimensions.

The second case I found in a post in which Zen Mod responded that it would work for an F5. This case is cheaper but appears to have smaller heatsinks than the first case.

Thoughts anyone?

Regards,
Dan

Regarding the Antek case...

I'm going to say no, only based on experience. My F5 heat sinks are 13"x8"x2" each and use 4 of them, two per channel. When the F5 gets warmed up after about an hour or two, the heat sinks are hot. It gets close to the "...if you can hold your hand on it for 5 seconds" rule. In the summer, can only hold hand to it for 5-6 seconds.

You want some padding to have an amp with a longer life span. It's a shame, because it's a real nice case for the money and Antek is a great place to do business with, but it's just not right for this project, in my opinion. Someone else may disagree with some exacting scientific principle.

DIY is going to have their own case designs. Not sure when they will be ready though. Hopefully soon.

Hi VDI Long time no speak Yes, we'll soon have some great chassis available and we're just about to place the order having finalized the details, but as it's coming by sea it will take around 2 months to see it in the store. The new diyAudio store has a form on the front page you can fill in to get notified of new stuff in the future. The diyAB "Honey Badger" AB amp will however be in stock in the US within a few days, along with a power supply board and a soft start / speaker protection board.

Even though I have all the tools to build a case. I find after I buy the materials, put alot of hours into preparation, and then add the cost of anodizing. It may be cheaper to buy a nice case.

I agree. However, I have a nice set of heat sinks and will be forced to build one more chassis on my own.

Strange, is this a stock F-5? Mine uses 2 M&M Metals heat sinks, about the same size, I only use 1 per channel and you can keep your hand on it as long as you want. I believe they are 12" x 8", fins just over 2"...yes I have measured temp on the mosfet.

No protection, no thermistor, but I built 2 F5s with the same heat sinks. The first was all original. They both get hot after a few hours.
