looking for a chassis

[HooRide]

Hi all, I am looking for a chassis for my PGA2310-based preamp to complement my RME ADI-2 DAC.

Anyone know of anything even remotely similar? If it comes down to it i'll have to draw it in some CAD software and have it specially made.

Thanks.

if you go the specially made route, check out protocase.com they're a little expensive but cool for prototypes and one-off projects. and fast too.

Hi.

What you need, is a "1U half width rack-mount enclosure"

Have a look at Hammond: Hammond Mfg. - Rack Mountable / Table Top Enclosures (RMCS & RMCV Series)

I am using a Hammond RM1U1908SBK for a project, and they are pretty. They are also rather expensive, and the panels are not flat. The RMC series are not as pretty, but they are less expensive and I believe the panels are flat.

Thanks all. I wound up getting a RMCS9018BK1. It's not perfect but it'll hold me over until I decide what I really want or have the time to whip up a custom design for something like protocase.

Now all I have to figure out is how to get a perfectly square hole cutout for the LCD...

What size hole?

What size hole?

The inside dimensions of this LCD module are 2.5" wide and .53" tall. I suppose I could use a dremel cutoff wheel but I don't think it would look as professional as I'd like. Any suggestions?

If the size were close I was going to suggest a Greenlee chassis punch. Greenlee makes a punch 2.559" wide but it is 1.378" high. I have a nibbler that I've used for rectangular holes, but in my hands the edges turn out a little rough. Another method is to drill a row of small holes along the inside of the rectangle, break the center free, and file down the sharp points.

You could always get a milling machine or maybe use a milling bit in the dremel. I don't have a milling machine but I have a new drill press, and if I were wanting to make a rectangular hole I would consider abusing the drill press with an edge milling bit. Worst that would happen is a broken bit in your face and a ruined part and damaged drill.

Perhaps the best advice is to avoid parts that require non-round holes.

If your prime concern is "front panel look-alike", why not use a standard rack chassis, and go with a front panel from (ta-daahhh.....) Front Panel Express. With FPE, you design it on line, and they will cut/mill/drill/anodize/stencil/label to your design. You sould be able to get a pretty good match to your DAC (depending upon your draftsman talents). FPE prices are pretty reasonable (aluminum panels....) and they provide fast, fast service.
