I've just now found this while searching online for cheap 500 series racks..
How did I completely miss this thread for so long??
I'm in line with everyone else for one of these babies..

@ volker
is the PSU separate from the rack?

depends ;DDIYnoob! said:
the backplane can be used for a standard 15pin Rack with XLR connectors at the back, powered from any API 200PS compatible external PSU (this would be an API 500-V like Rack).
the same backplane can also be used for 15pin or 18pin (or mixed) Racks, with an internal PSU PCB and "remote connector PCBs" (either XLR or SubD).
depends on the metalwork Sahib comes up (I don't think you can do one case for both options, these are two separated cases)

Birthday of two things.
First mine. I stepped into 49th year of my life in this world. However, I am still so young and good looking that if I posted my picture here you would all fall into depression. But I don't want to do that as Analag is already feeling depressed these days and that would completely finish him off. Also we still have that 30 tube project to complete.
Second is GDIY511 and GDIY512 cases. Picture is for GDIY511 but 12 is the same, except 12 slot. I have just collected the protos from the fabricator and it looks all good. They are not powder coated yet as I still have to work out the location of the D25 connectors and fit Volker's pcb to make sure everything is working out.
Top, bottom and back cover are all 1.5mm steel and both sides are 2mm steel. Side screw mounts are countersunk so that if the units are slotted into another frame there is no clearance issue. Additional holes on the sides are M4 screw holes for the rack ears and rubber feet. Mount the ears, it is a rack unit. Mount the feet, it is a portable unit. However, I still have to tap two holes for the handle but I have not selected a handle yet. Also excuse the countersink screws at the backplane which are temporary.
These are external psu version. Next I will order the prototypes for the internatl psu versions. However Volker and I will have some work to do on these.
I am off to watch my son playing football today afternoon. What a day to have a birthday.

Congrats on your birthday and the birthday of the GDIY511!! ;D ;D
Your pics look beautiful. My gosh this will be sooooo cooool!!!
One question, and I'm sure you thought of this, I assume the rack ears will be forward/proud of the frame by 3mm or 1/8" so the module faceplates are flush with them? Will they over-lap into the rack to cover the bend on the L and R sides?
This is amazing. Thank you for your hard work and for posting these pics
BTW, If I posted a pic of my fat, 43 year old self, you would feel even better about yourself!
Cheers, Jeff

I can send you a completely populated Backplane for testing if you want.
btw, if you want to add SubD cutouts we would need other SubD PCBs, those I have made won't fit here.
Nice work my friend.

Thanks to you all.
My son's team did not win. I have already disowned him and he is walking back from the school. And if the tea is not on the table tonight at 7 o'clock sharp wife will also get her P45.
Jeff,
That fold is 6.75mm wide and I had to have it because I did not want the screws protrude into the module's work envelope. Also it would be advisable to lock the mounting screw for the handle internally with an additional nut. When you have 11 or 12 modules fitted onto this case you do not want to rely on the screws only biting into 2mm thickness of the side plates. Plus consider the weight when we have the onboard psu.
I will make the rack ears myself. We have two options.
1. I can machine T section aluminium in 3mm thickness to go over them and become flush with the modules.
2. I can make 3mm plastic strips to infill the gap. This could be preferable because I can install 5 LEDs on one side to indicate the status of the power supply, and have GDIY511 (or 12) engraved on the other side. It would look cool.
Volker,
It would be a good idea to send them to me. But hold on at the moment. I'll drop you a mail.
Yes, we will need to work out the D25 pcb again. There is no space above. However, there is no reason why we should not have them below. We have to check the length of the off-the-shelf ribbon cables.
We are full on with this project now.

So is there any indication of costs? I assume that it should be less than the commercially available options or else you wouldn't have continued this far..

At this very moment I can not give any indication of cost because we are still waiting for quotations for the connectors etc. but we are not too far. Bear with us for another week or so. However, I can say that the final price will be considerably less than the commercially available ones.
