    Yep, buy that. There are lots of kinds to choose from, not just Dremel. You can find El Cheapo ones, for about $10, just to try out. Once you've used one, you'll wonder how you ever lived without it. I wound up with the Ryobi version that uses the standard 18V Ryobi batteries, but it's no lightweight. Once in a while, the El Cheapo is just the light little tool I need.

    When you get the Dremel or Dremel clone, get safety glasses. These little buggers can sling chips fast, and in all directions. Even the ricochets can hurt you.

    What is a dremel? Yea it was so bad, I dont ever open my windows and after 3 hours the smell was still in the room. I had to open the windows and air it out for about 1 1/2 hours. I also did the same thing to cut the same holes in the sunvisor and it uses this realllllyyyyyyyyyyyyyyy thick plastic that smelled almost toxic.

    AHHHHH is a small saw. Thats cool, I think im going to do that. It will be faster then melting it too, although I think Im doing with most of my plastic modifying work.

    The dremel is more then just a small saw. It is the best tool in the world. Not only a small saw but it polishes, drills, routes. There are many attachments for it. Buy plenty of the cutoff saw blades. You will need them as they will explode into many little pieces if you are not steady with cutting And rdholtz is right, use glasses!!!!! I cant remember how many times i say oh it will be quick i dont need glasses and then boom shards of cutoff blades into the face! Well no more, glasses all the time.

    I purchased the metal saw blade and it works pretty good for plastic without melting it. The cutoff blade sometimes builds up a lot of friction while cutting and causes the plastic to melt a litte. The metal blades seem to cut cleaner. But they do cost a little more.

    Also, if heat is going to be an issue with your system, make sure you monitor fan failures or at least cpu and motherboard temps if possible. You only really need to keep the components inside you carputer case between the high and low temps of there temp specs.

    Crazy thing is, my whole life with computers i've never had a computer fan go out on me....I did have a video card fan break off but the fan was still spining. I say this because the last 4 years all i've ever heard of is fan problems at my work...i would say more but you can never be to causious about what you type online these days!

    That said extra fans for protection in case a fan goes out is always good.

    That plastic smoke doesn't just smell toxic, it IS toxic. Here's what I wrote in my worklog (post #58):

    Plastic Welding -- Gotta Have Ventilation for Smoke

    Good ventilation is an absolute requirement for this plastic welding. It's a smoky process, but it's more than smell that's an issue. I've been reading that breathing the fumes from it can result in chemical asthma -- permanent chemical asthma, not just something that goes away overnight. For people who already have asthma, plastic welding might be a process to avoid.

    One thing is for sure: you really don't want to do this inside your house. I had to figure out a way to get the smoke and fumes away from my workspace. I started out using a 24-inch fan blowing out of the garage, but it wasn't enough. This stuff was like smoke from a campfire -- it seemed to follow me around. Now I've rigged a smaller fan right on the workbench to pull air away and direct it to the bigger fan. I'm breathing easier, now.

    The Dremel is a good way to avoid the smoke. When you gotta make smoke, do it in really good ventilation, and don't breathe the smoke.

    OMFG thats terrible. Im going to buy the Dremel this weekend.

    On another note, I put the PC all together. The setup was really weird. The fan that i thought blew air into the case, actually draws air out. The way the case is designed is that when the fan blows out, it sucks air through the vents on both sides of the case. The processor fans, blow the air up, not down. I decided to close the case and install a temp monitoring software. It had 5 tempature points, all which had an arrow pointing down which indicates that the board is to cold. Infact all had the cold arrow, even the HDD, which is in a weird place (mounted under the DVD rom in a small space with all electrical wiring going through there.). It did have one that said it was to hot, but I cant figure out what it is. Its not the processor because it has its own area for that and it says cold, so it must be the PSU temp.... but when i touch it, it isnt even warm, so I think it may be a glitch. So all in all, I do not need to add a fan at this moment. I am worried that once the case is upright (the exast fan will be at the top) that air flow will flow incorrectly, so what I am thinking of doing is having it blow in and one fan at the back bottom blow out.

    A lot of these fans can be flipped over. If the top is one you can flip, I suspect you'll want it to blow heat out, because then it's simply adding force to the natural upward flow of warm air. You may find that just the fan at the top can exhaust enough heat to keep everything happy.

    What I decided to do is leave the top fan exhausting the air, and I also put one at the bottom exhausting air. I then installed a software called SpeedFan to test see the conditions. All show a blue arrow pointing down which means too cool. I did have an issue though were the GPU was showing it was on fire. So I took the fan off and it went to normal, but when I would play video it would say over heating. I decided to take every heatsink off the board and found that the thermal past on the GPU was hard and wasnt making very good contact with the heatsink and GPU. So now I am cleaning the thermal past off the processor, audio processor, and GPU and redoing them all with high grade thermal paste.

    Here are the numbers for the case tempature with the case open.

    TEMP1 (PSU): 32C - 34C
    TEMP2 (VPU): 30C - 32C
    TEMP3 (AUDIO): 25C always
    HDD: 31C
    PROCESSOR: 28C - 32C

    I think this is really really really good for a Dual Core Processor with a powerful GPU. I did have to add a fan to the GPU. Without the fan, tempatures were reaching 48C at idle and 52C (over heating) while watching movies, 3D graphics and what not. I have also decided to rethink how the case will cool its self. I want the same tempatures to be reached as when I have the case open, when its closed. I added a extra case fan at the back, that will be removed. There is also a fan next to the HDD, that will stay there since the PSU cables and IDE to SATA converter split it from the rest of the case.... On top of the case I will cut 1 large hole to hold one large fan, or 2 holes to place a fan over the PSU and one over the MoBo.

    Temps look fine.... my desktop cpu runs around 36 celsius (mobile processor even) so looks like your set with your setup. I'd just stick with how you have it since "it ain't broke" anymore =).
