Okay, this is my first real modding-related post here, so I hope this goes to the right forum. I'm currently planning and later on going to implement some usefull mods to the case of my server. Currently the project is only in the planning stage, so comment as much you like. But first a little disclaimer. The server is located in a storage closet where no one can see it unless he/she especially wants, so the mods are going to concentrate on udefullness, not appearance. So I'm probably not going to paint the case, install any lighting or something like that. (Although some internal case lighting with external power source instead of the case PSU could be nice, because to closet is kinda dark, thus making hardware upgrades pain.) But on to the topic... The case itself is a Chieftec TX-103 tower case, which is pretty nice for a server, even though it's not a "real" server case and it's not the most beautiful case around. Here's a picture of the case: (I forgot to use flash so the picture is a bit blurry, but gives a general idea still...) For those wondering why there aren't any blanking plates in the 5.25" bays, here's a further explanation: As the usefull HDD bays in the case ran out, I had to install the two drives in my raid array to the 5.25" bays, together with adapters shown in the picture. As the drive rails used in Chieftec cases are made of plastic, it pretty much stops the transfer of heat from the drives to the case hull. That's why I had to install a 8x8cm fan for the drives, as seen in the picture. Isn't that lovely installation? So now we get to the first mod planned for the case. As there's not going to be any real 5.25" devices in the case, I'm going to replace the bay covers with a piece of plexiglass. The plexiglass is going to have a place for a 12x12 cm fan, so the airflow will cover pretty much the all four bays, thus making it possible to install two more drives in the case. I'm still a bit unsure about the design of the plexiglass. Two basic ideas I've had are: a) drill the area where the fan will be full of small holes, forming a nice grill. However, I feel that this would still block the airflow and maybe create extra noise. b) drill a 12cm diameter round hole for the fan and then cover it with a "regular" fan grill. I don't have a picture of the grill but I'm sure most of you will get the idea. Personally I'm going towards the b choice, and I already did a quick planning of it with sketchup: So now I'd like to hear some comments about the design. And those who have more experience with plexiglass, is 5 mm thickness enough for my project? I bought a scrap piece with that thickness and I wouldn't like to buy more now... After I've finished the current project I will probably start planning how I could make the airflow through the case even better... I'll post pictures of the current cooling setup soon.
