X51 Case swap Help Needed


May 20, 2014

So im case swapping the x51 into a corsair 350d, and installing an h55 water cooler and corsair 600w psu

So far I have the main mobo and the water cooler installed...the ssd, and gpu connected.


I am at a dead end with the front panel connections from the case to the mobo, the Power sw, reset switch, power+ power - HDD light.. I am unable to get the machine to boot. The furthest I got was one of the front panel standy lights was on. The fans do not spin when i turn the psu on.

Anyone out there do a case swap on the 51 mobo and can tell me the correct way to plug in the front panel leads so i can boot? The colord ones on the bottom right.. I really dont want to have to even attempt to plug the x51 together again. I think its just the final part of connecting the leads I know the psu is good, the front panel standy light came on.. Just wrong configuration

Update* Succesfully swapped the x51 case to an obsidean 350d. I found the correct front panel settings and everything works fine.

Here it is, just need a few fan splitters and fans to install and and get some sleeved sata cables for looks and its finished...

USB Front panel 3.0 adapter: http://www.amazon.com/gp/product/B009SJCPO8/ref=as_li_tl?

Sata Cable extensions: http://www.amazon.com/gp/product/B003ZDNY0C/ref=as_li_tl?

Now, the only things that are REQUIRED, is the PSU, and the sata cable extensions. Everything else is optional.
But you will def want to get the fan splitter cables to add more fans, without it you will only have access to one fan and that will be the cpu fan. With the fan splitter cables you can add more fans. If you want more then one fan + the cpu fan just get a fan splitter cable that has more ports on it. I have been doing fine with the water cooler and one fan.

and the front panel ports to get everything connected correctly is here> https://www.youtube.com/watch?v=zDmp1urswjE

Connect your front panel connections just like in the picture from the case to the mother board and youre good to go. This was the hardest part. You will lose the cd drive, but you can install an a regular one if you wish. I left mine out.

And if you install and 780 like I did, you need to update your bios from the dell website or it wont work.

i am trying to decide whether to do this case swap approach myself or buy another PC altogether at around £2000 that path isnt cheap!

I want the GTX 780Ti but that means a bigger PSU, so can I ask as you seem to have completes the build and transfer, is it difficult?

It easy to do i did it but i did not use a fan splitter cable i got the case fans that you can hook directly to the PSU that's the best way as the fan plugs on the motherboard are not designed to split. Also all you will need is the motherboard more ram if you want it and a better GFX card if the one you have is not to your likening, and a really good PSU don't skimp on the PSU.

There is one thing he did not tell you when you do this every time you boot you will have to hit F1 or you can go into the Bios and tell it to not halt on errors, as you will have a power sensor error. Don't let that alarm you its nothing to worry about. So there you go is simple just gut your x51 and leave everything else in the case but your GFX card and you will not need the GFX card riser the thing it's in now. just the motherboard and graphics card and hard drive. pull the motherboard out leave the memory on the board as well as the cpu and fan it will all work in a new case, pull the fan scoop of the fan it will not work in another case it just unscrews from the top of the fan.

Also be really careful when you plug your GPU into the PCI E slot as the front of most GPU will hit a capacitor don't push really hard as you don't want that to snap of the board, so really push light and gentle on the card just enough till you hit a bump that would be the card hitting the top of the capacitor leave it at that. If you want to be creative you can do as i did and trace the back of the x51 IO cover with cardboard and make a make shift cover for the IO ports, that way dust don't get in the computer i used a all black piece.
