DELL XPS - BTX to ATX mod.

[d_stilgar]

At the end of last summer I got a DELL XPS case at a WSU surplus sale for $15. Now that the school year is over I'm finally getting around to modding the thing from BTX to ATX and moving my current rig into it.

Here are the before pictures. It's a really solid brushed aluminum case. It weighs about a million pounds and looks great. The only problem is that it is BTX standard.

Here's the back, where the problems are and the only part of the case I will be changing at all.

. . . And the side. The case is designed to look like it's leaning forward.

I started by removing the motherboard tray.

I'm going to try and salvage that front bit. It holds a fan and I'll mod it to hold the radiator on my Coolit Vantage.

Here's the new motherboard tray. It's a Lian-Li something . . . It's ATX standard and a nice red anodized aluminum. I got it for $50 at performance-pcs.

Next step was to remove the back plastic plate. I will have to cut it apart and glue it all back together so it conforms to the ATX standard of everything else.

The next step is where the modding really begins. The back metal plate was riveted to the case, so I had to drill through the rivets to remove it. I'll have to buy a rivet gun to get this thing back together. It's about time I got one.

And from the metal backplate I drilled out the rivets holding the IO shield. This will eventually go, but it has a neat LED array at the top so you can light up the back of your case to get things plugged in and out. I'll be recycling that.

Next, I marked out everything that needed to be cut out from the inside so the new motherboard tray can be mounted. I cut everything out, did a few test fits, then drilled and tapped a few holes so the motherboard tray would be flush and secure. I'll probably add a few more screws to this before I call it done.

After the motherboard was mounted I marked where the metal back plate needed to be cut. I would then cut it and hold it up again to make sure everything fit, and then made more adjustments until I liked the way it looked. I replaced a big area I had cut out for the new expansion slots and glued it to the location of the old ones. This is good enough for me at this point. The plastic back plate that goes over this will have to be modified as well, but will cover any imperfections the metal plate has.

That's all for now. I need to get 5/32 rivets to get everything back in place, and I need to start and finish the plastic back plate. After that though, this will be finished. The whole point of this mod was to take the BTX case and make it ATX. It doesn't have to be pretty since it's the back of the case, but I'm going to do my best anyway.

I've always wanted one of the XPS cases. I'd kill to get it for $15.

You had me at "Dell"


Intrigued.

I'm not against selling it when I'm done. I have way too many cases around here.

And I might take you up on it

Now, to interface with USB, headphones, and power.....

The next step in the project was to mod the back panel plastic. This was about the same as the metal, but instead of using a grind wheel on my dremel I used my scroll saw. It was easier to cut and the blade on it is thinner, so I would lose less plastic.

Here's the finished plastic panel. The only thing left for the back panel is to get the original I/O shield shroud and put it in place. It will go on the inside of the case and I will rivet it in place, but I'm going to wait until I have my motherboard out and ready to install so I can do this exact.

It really turned out good. To get this result I cut the plastic from its original position, but I couldn't just glue it in a new place. There wasn't enough plastic there to do it, so I had to add more. I got out my 2mm sheet styrene and just strips to the appropriate length and width, painted them high gloss black, then glued them in place. The only problem with this is that super glue leaves a white residue sometimes. Most of it should clean up (which I haven't done yet) but there stands to be some white residue that remains when all is said and done. So here's the question, do I repaint the whole thing in gloss black, or do I just leave it? Part of me really just wants to see this thing finished. These pictures show some of that residue.

Near the bottom left of the case is a new hole. I'm not sure what I'm going to use it for. I could use it as a blower exhaust or I could put some fan/LED control knobs there. For now I'm going to do nothing and leave my options open. Ideas?

On the inside of the case I cut out part of the original motherboard tray that held a fan or radiator and put it back in its original spot. This might just hold a fan in the end, or I might use it to hold the radiator on my CoolIt Vantage.

My other option for holding the CoolIt Vantage radiator would be the original CPU cooler shroud, but that will leave me with the problem of figuring out how I'll remount it onto the case. I would prefer this though since it would turn the whole thing into a true all-in-one liquid cooling solution right on the motherboard.

Agreed! I removed the PCB at the front of the case that controls all the front ports and traced the leads back to that mini version of an IDE header and then wrote down everything. All the surface mount LEDs share a common ground. There's power, network activity, Primary HDD activity, and HDD activity 1-4. For the USB and firewire I just got on ebay and got an official version with standard connectors to standard motherboard headers. Thank goodness DELL did one standardized thing. I couldn't for the life of me get the front panel LEDs to light up. I tried every combination of pins on the mini-IDE header, but nothing was working. There's probably something else that controls them on the board. To get this to work then, I just went straight to the source and found which pin was the common ground then poked around til stuff lit up. There are actually three different colored LEDs in the front, red, green and blue, so with some potentiometers I'll be able to vary the colors, mix and match to get pretty much whatever I want.

Thats it for now. I'm waiting on some parts to come in but then I'll get this finished up and loaded with hardware to boot up and use!

You finish this yet?

Alright, so . . . here's the deal. I've finally decided that I just need to get rid of this. I'm going to keep the red anodized motherboard tray, but the case I'm selling. It's mostly there as far as a conversion goes, and I'll include the pinout (at least what I've figured out) for the front panel. It's more or less finished, but I worked on it yesterday trying to get the front LEDs to work via a fan controller and some switches (for customizable RGB lighting) but couldn't get it to work. I think I'll just end up putting some of my new parts into my Cooler Master Stacker 830 and sell this off. $100 shipped. Shipping is going to be like $70 of that.

Too bad mate, it would have been an awesome mod...but respect for your decision...
