    well i just bought a 145W ½ sized ATX psu for £40 (so i can swap the 80mm for an ultra silent panaflo) but im having a tad of trouble getting tinted/opaque (like the pcmods windows) acrylic/lexen/perspex.

    Ive emailed a US company and a UK company that was recomened on here and the uk company couldnt deliver to my side of the country :( and told me to go to: Amari Plastics or Plastics Plus (got to find where these companies are) and ive had no reply from the US one yet. Ive goto go down the big B&Q diy warehouse/store in cardiff to see if they do sheets of the stuff (probably not tinted though).

    I read in another article however - if u dont make the sides EXACTLY flat then the acrylic cement wont set? so he had to use screws :( what are your thoughts?? is there any other way for getting it less *exact*? cause i dont want to fubar up some sides when i make it.

    all will be revealed in the construction techniques article, but I think that drilling and tapping edgewise into your material is substantially harder than getting the edge to be flat (hint sandpaper and sanding block).

    i spose the more effort u put into makin it flat too - the more square and even your box will be?

    anyhow, cant wait for the 2nd article :D

    IfF you have uneven edges, your cement will set fine, but you'll get gaps, and it will run out of them before it sets. I think that's what he was wrestling with. I'll show you a photo of a test piece later after I get home from work.

    linear, you're article did inspired me, but not for an acrylic case ;)

    as I'm making my "computer-room" now, (actually my room filled with PC's) I want 2 uniform cases for the 386 and 486 of me, which I'm not planning to use but just for fun. Thatswhy I'll be making a wooden case, and then paint it black. I don't think it will be as hard as an acrylic case... But I hope your future articles will help me some too ;)
     
  7. Awesome Article, as soon as my skill improves with 10$ cases I may, some day, try building a case from scratch :)
     
  8. Double post :/

    Materials

    Nice article. Agree that planning is key to success and looking forward to the next article.

    Any ideas where I can buy perspex/polycarbonate, preferably a national supplier as I intend to follow the articale and build a case

    Thanks for the info. It looks like perspex is not that easy to get hold of in the UK. I've emailed a few sign makers locally to see if I have any better luck. Will post any progress.

    This may help someone for future reference. I wrote up an article on my plexi case as well, for those that have not yet seen it.

    You can find it here: Plexi Article

    I've managed to get some responses from local sign makers with a variety of prices but the following is the cheapest:

    Sheet size is 2030 x 1525mm

    3mm = £53.71 + vat
    5mm = £75.65 + vat

    and they are prepared to supply part sheets, maybe even cut to size. On this basis I would expect midi tower to cost £20-£30, depending on design complexity for perspex material which I don't think is too bad.

    What about static?

    I've been wanting to make a clear case for a while now, but what about the static electricity buildup? How do you deal with that?

    Been looking at making a acrylic / perspex case for a while but have had a real problem sourcing the material.. (UK)


    www.diyplastics.com

    Was the only real solution I could find...
    The only problem being the cost :(

    Anyone find anything better? Please?

    I suppose it isn't too bad.... But I'm still looking... B&Q do some perspex but it is very thin and quite expensive, would cost a lot to make a case from it...

    One thing though, has anyone thought of heating and curving the plastic? It doesn't have to be square, you can be as inventive as you wish, I would suggest a wooden jig and some resistance wire (check out Maplins for that.. I think it'll heat under electrical load..)...

    Ahh well, I hope a nice cheap solution is found... :)

    Re: What about static?

    There is a tendency for static to build up on the pieces, but applying a polish such as Novus #1 plastic polish does a good job of reducing the tendency to build up a charge.

    One last thing, when heating the perspex / acrylic heat it just enough, too much and vapour bubbles form :(
