Not really, my P3 had a front cover that slid all the way up, and covered the power/reset buttons and the floppy and CD drives. I also think it had two 3.25" bays instead of one, and the LED display was to the left if memory serves me right. I wish I had a picture of that P3... it is weird how I can't find pictures of my older machines. That is a mighty fine case too, though.

Btw have you cheked the solder joints of the PS2 connector? Also, some SS7 motherboards do have legacy support for USB keyboards.

I did check them and they were not shorting out, and you are right, this one has two USB ports, yes only two but for now I do have only a wireless keyboard and mouse (I plan to use a wired set instead of wireless), and I need to get some parts because the Sound Blaster Live and the Trident card that were in there are being used by the Pentium 266 (Video) and Pentium II (Sound)

And also I need to get IDE cables and stuff like that (I do have a CD drive and a old Quantum 5.25" 2 GB HDD and a ALS 4000 soundcard) and maybe at some point I will have the computer working again :3 also is a lil' bit hard to get the best vintage cards and the best video cards like the 3DFX are very hard to find and expensive to buy (We here in Arg. have a lot of inflation) so as of now I will be keeping to save some money, so the Pentium II replaces the K6 coz is 50 MHz faster than the K6 itself (But one advantage is that has 3D Now integrated on it )

I think I did saw that style of case that you are mentioning many times in the front of my eyes, I believe that the mayority with that style are AT cases or maybe it was a universal one meaning that accepts either Baby AT, ATX or Micro ATX owo

My case was a tall ATX one (I can find Baby AT cases like that, but they do not look the same) with three 5.25" bays and two 3.5" ones, and the PSU was mounted like in newer ATX cases (on top as an exaust, not above the mmotherboard blowing air into the processor). I'll hunt it down eventually =)
Don't stress too much about Voodoos...This seller put a bunch of reasonably priced stuff up (MercadoLivre.com.br), and boy... his Banshees sold almost instantly. I was able to grab a Voodoo3 3000 and I like it very much. Sharp desktop image and good performance for what I use it for. He's got a Voodoo1 for sale, but at a higher price. That one doesn't look like will get snatched anytime soon (unless I get some extra cash in the near future, that is xD). My Voodoo2, though, was bought from Korea (through ebay) with free shipping, and it was still cheaper than the ones I've seen here in Brazil, but it took a while to arrive. Unless you wanna mess with Glide, though, just snatch a cheap nVidia card (check the voltage regulator if you get an AGP card). MX4000s are cheap, plentiful and will probably offer more OpenGL performance than the K6 can tap into anyway.

Btw, for gaming even a 550MHz K6-3 can't match a Pentium II 450MHz. 3D gaming does use the FPU, where the P2 is much better, and even 3D Now! won't offset this completly (and there are plenty of games that do not support it). Still a fun platform to mess with.

The low score is because I have both caches turned off to run it in 286 mode, as Phil says, with MB cache is 386 and with the processor one is a 486 and both turned on is 266 MHz full speed (Maybe on the cache stuff I'm inverted on the options and processors)

I don't believe Phil has said such thing. I don't think you can get a Pentium MMX running at 286 speeds even if besides disabling MB and CPU caches you make it run at 50FSB x 2. A Pentium MMX 100MHz with both caches disabled will more likely be running at 386DX-40 speeds or even faster, like a 486 SX-25.

My K6+ running at 100MHz with all caches off runs just slightly faster than a 386DX-25.

Maybe I said the speeds in reverse order, I don't know u.u and I see :3
One thing I notice is that when I disable both caches the system is more slower letting me to play speed sensitive DOS games so lets say, when I go to the BIOS and disable both caches means that I'm decreasing the FSB speed?? I'm asking because enabling and disabling both caches or one by one is affecting the processor's speed and the computer boot up sequence is much slower and I don't see that the processor speed is getting affected by this

Disabling caches doesn't change the CPU clock speed or the FSB speed. It's slower because without the memory caches, it effectively makes the memory system slower. The CPU is still running at the same internal clock speed, but every time it accesses RAM, it has to wait longer for a response.

With both caches disabled, the CPU is always directly using main memory. Main memory is very slow compared to the CPU. Normally the CPU tries to use the cache memory instead, which is much faster, and then the cache synchronizes with main memory in the background without making the CPU wait for it.

Oh, I understand better now, thanks :3

On the other hand, I added a ALS-4000 soundcard to my P200 MMX machine just for curiosity and it did work, but games like Street Rod II doesn't detect the Adlib emulation, just goes into PC-Speaker mode and Wolf3D just makes the soundcard crash when is going to play the door open sound effect, could be a IRQ conflict (The BIOS always adresses IRQ9 for any PCI soundcard that I install, happened to me on the Pentium II, both of those have AMIBIOS that were programmed the same year and date as specified in my second post on the first page) or maybe could be a misconfiguration??

For a PCI sound card its IRQ and the IRQ for the Sound Blaster emulation are not only independent, but should not coincide (and that IRQ should be free). That should hae nothing to do with AdLib emulation, though, since that only uses IO reads/writes. PCI sound cards are a waste on DOS systems anyway: too much trouble for no gain.
