Recommend me some parts

Thread Starter 
I'm getting ready for my Buffalo II build and could use some parts advice. This will be my 4th DIY project but the first where I don't have a BOM to work from. It's going to be a pretty simple config, with the BII board, the new IVY board, their Toslink module, RCA outs (single ended), a Placid and Placid BP running off their recommended 1 transformer each. It should easily fit into a Parmetal 12x12x2 enclosure. So here are my questions:

- should the AC in be fused?
- can I go with an integrated IEC inlet/fuse/switch?
- is there any value to having an integrated line filter?
- any specific recommendations for modules

Thanks in advance for your help.

ac line should ALWAYS be fused!

integrated iec's are great, they save space and drilling.

integrated line filters work both ways, don't forget. they stop bad stuff getting INTO your ac lines from your equip! not just the other way.

Does it matter if the switch is single or double pole? Schurter makes integrated IEC inlet/fuse/switch units but I'm trying to figure out if single vs. double pole matters for this application.

Thanks for being patient with such a basic question.

You only need a single pole for switching AC. Some countries fuse both the hot and the neutral, and probably switch both as well. Not quite clear on this, but I was told that fused neutral violates electrical codes here in the states. Someone with better knowledge can fill this in...

Agreed, 100%.

One would have to be pretty careful given the 2" chassis the OP mentioned. Not saying it can't be done, but it could be tight. I know the integrated IEC that I used on my RAKK DAC fit, but just barely. It was the same size as ones that use a fuse, I just opted to have the switch integrated into the jack instead for this build.

Well, he could mount it horizontally rather than vertically.

Yes, it would still need to be a snap-in type though as the flanges could be every bit as wide as the body of the IEC is tall. I was just showing one example that worked, not the only example.
