Phil questioned the cost values for the Ren-T and I double checked my BOM and I had both transformers listed. Took out the Tamura and that drops all parts in the BOM to about $20 and a typical Case 3 build down to about $18.75. Now of course anybody who decides to leave off the power entry module and AC cable can also save another $9 but that is not what I intended for the chart. The chart shows an estimate of what the listed BOM will run at Mouser.
Also, I tilted the estimate a little high so that when someone actually went to buy the parts and it came in cheaper than the chart they would be happier than if their total was higher. I also didn't consider shipping directly into the numbers but it definitely would also push the number up.

Are you considering the PCB as part of the price? Maybe that's part of my difficulties, I was considering just the parts. The price that I was thinking was perhaps about $3.00 for the connectors, $.25 or so for the diodes, and using a surplus transformer that I bought for $3. So I was leaving off the power entry module (I used a pair of wire nuts), and the end of an old extension cord that I had laying around.

Maybe the best thing to do is to say what the basis of the prices is (one-off ordering from mouser, not including shipping), and that the prices may vary quite a bit.

By the way, the little icon with the scrawl inside it just above the edit window puts your signature and date stamp on your edits.

The cost of the Renard8 should be essentially identical to the Ren-C, so I changed the numbers for the Renard8 to agree with Ren-C. Also, I think that the Renard64 numbers are about twice what they should be, but I haven't had time to check it out carefully yet.

This is why I took the time to make this as a table in the wiki and not just a screen shot of the table I made in MS Word, so it can be changed if needed. I only ask that if numbers get changed that it is based on what a new user would have to spend, not based on one's ability to scrounge parts. New users will be going off of the BOMs and if they are wrong or have too many options they may order too many parts. Thats what happened with the Ren-T and apparently the Ren8, I didn't remove some of the optional/duplicated parts (Ren8 BOM has 3 different RJ45 connectors listed). But the Renard64 BOM with LEDs and ZC opt1 (I believe the most common build) comes in at about $75 with Mouser.

I haven't looked into it yet, and it may be a while before I get to it. But it still seems quite high, unless mouser has drastically increased the price of something or other.

BTW, do those prices include the PCB, or not?
