    HP Proliant DL380 G4 575W x 3 - $5-$25/piece
    These fit perfect in the case as you can see in the pics without taking them apart. @rundmg is now building his similar to mine using the bigger power supplies like @Nick Moxley uses, so he will have pictures once he is done of his took apart and mounted in case.

    Wiring:
    I used standard wiring from local hardware store. Power lines to motors are 2 wire 14awg. Custom estop cable uses 3 wire 12awg and 3 pc cable ends that are 1ft and the standard 18awg.

    Great list, thanks so much for taking the time to put it together, I am sure others will want to emulate such a clean and neat solution, I know I will.

    Next time you have the Coolmaster cover off can you grab some more photos of the internal layout?

    Looks AWESOME man, BUT one concern i have, What are the Tamiya connector's for ? Those have a HIGH probability of melting and causing a Nuclear melt down. I suggest going with a Deans to be 100% safe. Fortunatly the tamiya's are cheap and so are Deans, But the difference in power handing capabilities is NIGHT and Day difference.

    Used those on the motor side, so far they haven't got hot, but thanks for the heads up I'll keep an eye on them.

    I took an old power supply and removed the internals/lid and then cut one side off and kept the fan in it. Then just mounted to the rail as you see in pics. Inside of case is pretty simple. I need to get a smaller usb hub and shorter usb cables for the inside to clean that up, I had ordered a bunch of 6ft ones and was wishing i had 1-2 foot ones.

    The case did have a cd tray which I removed to make space, would have make a good place to mount jrks but it had a lot of holes so I said frack it and removed it.

    All the screws I used came with the case are in a bag of spare parts. (Except for the nylon spacers and screws used to mount the jrks to plate, I need to add those to the list from pololu.com

    You can see in my finished pictures in other post; I was able to just screw the power supplies in via the little holes on the back of the case.

    Let me know if any their are any angles I don't have that you want to see.

    As you say the PSUs are a perfect fit!

    Getting to the JRKs is also simple, should you ever need to swap one out.

    When I created my 'computer dock' I added a digital touch screen fan monitor with alarms, to keep an eye on the JRKs temperatures. The Coolmaster case even has enough room to incorporate thermal monitoring if you wanted to develop it further.

    I might ramble too long in this one.... be warned!

    I'll start a new thread on here for it and also include the custom bluetooth rim build, and give you guys the 3d files to print for it as well. It will have 7 push buttons, carbon fiber paddle shifters, and 2 toggle switches. Total cost is under $200 , closer to $150 actually including the rim.

    The main OSW build thread is mainly on the iracing forums, and can't be copied to other sites. Here is a link to to a tutorial most people start with, also where I ordered my carbon fiber paddle shifters.
    http://www.ascher-racing.com/opensimwheel/

    After tons of research and pricing everything its a no brainer. One of the guys behind it and really pushing it forward with custom boards/etc just started selling a DIY kit.

    I made a parts list and my cost was going to be like $1200-1300 and 3-4 weeks of waiting for parts.

    This guys name is Ollie and he sells a full kit that is ready to be mounted into a computer case (most ppl use the same elite 130 cooler master) No soldering, everything is done. You just mount it all and connect things following his instructions and then reference the forums for the software side of setting things up. He has sold at least 100 kits that I'm aware of, might be closer to 200 now.

    Seems like he is 4-6 weeks out on orders so you just get put on a list and don't have to pay until your unit is ready to ship and he sends the invoice.

    My total price shipped from Germany is $1125 to US so it was a no-brainer. @rundmg has one coming too. I can get you his email if you want to get added to the list.

    Below is an image of a recent kit one of the guys got from him. Once his custom board is in production you won't need half the boards in this pictures though. Hoping my order will have it :) Obviously the laptop and soldering iron isn't included...

    It comes with the small mig servo, will do 20nm of force, some guys are pushing it to 25-29 but have no idea how long it will last pushing it over 20. From what I hear we are talking about enough power to break your wrists in a wreck if you don't let go when you go over 20nm. It's not so much the power I really want it's the level of detail this thing offers.

    Did you watch the The Sim Garage comparison video? It stirred up all kinds of mayham and trolling in the forums.

    Haha yeah I need to check that out, I've been popping the lid every so often mid race to check and feel the heat sinks to make sure we are good. lol

    So far it's been fine though, I've burnt enough jrks up for a lifetime.

    Awesome job on the Coolmaster case, VERY clean. Ya get rid of those 6' extensions and go for 1.5' or even shorter to clean it up real nice.

    F i really wish the Canuck dollar wasn't so Garbage right now or i would JUMP all over that deal....1300$ isn't that bad AT all.

    As for NM rating's on motor's.....I can 1000% agree that 20nm and up will break fingers and more than likely worse if your not careful......My CSW after the buhler upgrade actually injured my thumb on one of the first outing's....Not paying attention to how much force was REALLY hiding there waiting for me.

    here's the chart for sheer reference

    The resultant effect of the stronger motors is as follows:
    Stock motors @24VDC pulled 8.5 pounds@~5.38"R. So about 3.8 lbs./ft. (5.2 Nm) of torque.
    With the Buhler motors @24VDC pulled 14.5 pounds@~5.38"R. or 6.5lbs./ft. (8.8Nm).
    Buhler motors @30VDC pulled 18.25 pounds@~5.38"R. or 8.2lbs./ft. (11.1Nm). *****Mine

    New test:
    Buhlers @40VDC pulled 21.25 pounds@~5.38"R. or 9.53lbs./ft. (12.9N•m)

    @scalhoun , nice build! I'm also going with the elite 130 case idea as I wait for my OSW :)

    Do you still plan to post the 3D file for the back panel?

    Glad to see that 14AWG wire runs work fine for the motors at the length you have them at.

    @scalhoun Can I trouble you to export that back plate file into STEP or IGES format or a 2D DWG format? I will want to get it laser cut but need it converted to those file types.

    Does the original autocad dwg file work? I can look for the other format exports quick, just never used them so not sure yet.
