Has anyone ever converted a BTX case to an ATX case? - Page 2

post #11 of 20
what's the point in doing this in the first place? If you NEED BTX, it'll probably be cheaper to buy a BTX case
post #12 of 20
Could you post a pic of the case? If my memory is correct, the only way to do this is to cut out the entire back (i/o shield & expansion slots), and replace it with the back of an ATX case.

BTX's simply can't be flipped, they are upside down and backwards.

The only alternative to so this succesfully, is to modify the case to open from the oppisite side that it opens now.

BTW, you'll need a Dremel, Safety Goggles, Rivet Gun, Rivets, Filler, Time, Patience, Inginuity & Imagination.

Good Luck.

That is exactly what I want to do.

The computer has sentimental value, but I want it to be a REAL computer.

The motherboard in it is one of the worst I have ever seen.

I will try to get some pics up soon.

Thanks!!!

Cutting torch dude...oxy acetylene,that will do the trick.Then just weld a new back on the case and voila!I'm in for some pics.

To answer your question?No it's a waste of time and effort unless you are taking it up as a personal challenge.I am sub'd.I don't think you can.biggrin.gif

I hope you aren't trying to trick me into accidentally melting my fingers off with a cutting torch. LOL!

Okay, it has been awhile. I have managed to use a dremel to modify a few cases in ways that were more dramatic than the simple alteration of BTX to ATX.

For instance, I turned an old ATX case into an open bench tester for shooting videos of mother boards and video cards that I sell on eBay and Craigslist to prove they work.

This puts me one step closer to modifying the Lenovo.

Update (6/30/2011): Images and brief explanation.

The reason that I did this is that this computer was given to me by my college upon earning a degree. I want to keep it for sentimental reasons, but only if I can actually use it. However, the computer sucks. Sometimes it boots, sometimes it doesn't. It can only use 32 bit operating systems and will not even boot with more than 3 GB of memory. It overheats. The fastest chip you can use in it is a Pentium D 950. It can only take small form factor video cards and they must be single slot.

So, I converted it to a case that can use a standard micro-ATX motherboard. It was not as easy as you might think. I actually had to remove the motherboard stands with a Dremel. Then I had to carefully drill holes to put in conventional ATX spaced stands. I also had to rip the ATX case switch off of an old case and attach it to this one. The USB ports were originally designed to go in a PCI slot, but were mounted to the front panel. Finally, I had to completely saw out most of the back of the case with a dremel, then flip it upside down and screw it back in. To make the video cards and other expansion cards hold their position I had to screw a strip of metal to the inside of the case. This strip of metal was originally part of the cover to an older ATX case.

I'm happy with the finished product. It went from being a Pentium 4 with a 9800 GT EE, to being a Q9550 with a GTX295. It now boots every single time I start the computer and I can put any micro ATX board that I want to in the ATX case. Everything is firm and rock solid. It even gets great air flow. I think the chip idles at like 26 C and the card idles at around 45 C (its overclocked too).

I was even able to save the original motherboard, CPU, card, and memory. They now reside in a GATEWAY BTX case that I fished out of a dumpster two years ago and had in storage. Strangely, now that the school motherboard is in the Gateway case, it now boots every time and does not overheat.

Okay, I converted the IBM Lenovo BTX caste to an ATX case. It was kind of tedious.

I used a Dremel to:
  • cut out the back panel;
  • cut out all of the BTX screw mounts; and
  • drill holes for new screw mounts.

I flipped the cut out panel upside down and screwed it back on to the case so that it would line up with the motherboard.

I made a new switch & LEDs from parts ripped from an old computer. I worked a USB slot into the original USB header box.

It actually looks pretty nice and is currently running a Q9550.

Majestic_Lizard,

Nice work on the mod. I am actually attempting to do the exact same thing right now. I have a the same identical Lenovo case (got it from University also), and I want to convert it to mATX. I like the design of the case, and I don't see the point of just buying a new case because I will still have this Lenovo case hanging around. I want to find a use for it! Because all of its parts are totally shot, so the case is the only thing of value left in it.

Hopefully you can answer a few questions before I start:

-How long did it take?

-I have an ATX power switch, so I can use that, because as you mentioned the Lenovo power switch and front panel USB ports cannot be connected to an ATX. Did you find a way to get the USB ports to attach to the new Mobo?

-I don't have a dremel, can it be done without one in your opinion? (could probably borrow one though)

-Can you post a picture of what the back of the case looks like (after you cut and flipped it?). This seems like it is the hardest step. Where exactly did you make the cuts?

Sorry for the very late response. Off and on it took a few days. Altogether it was probably six to ten hours of work. Had I started off having a clear idea of what I was doing it would have been considerably less work.

I would recommend work gloves when using the dremel. I narrowly avoided removing my thumb. Also recommend using work goggles and breath mask so that metal shavings do not get in your eyes or lungs.

I don't see how one would cleanly remove the metal parts without a dremel. A professional welder could do it, but it would require skill.

BTW: I painted the back of the case black. It also has some antec 900 slot covers.
