It is time for a new shed/workshop computer. My socket A Athlon shed system, built in 2001ish, is just too slow. I want a computer that is fast, not to big, not too loud and that still has some room in it for HDDs and stuff. It also has to be very dust resistant and heat tolerant. Key parts are Fractal Design Core 1000 Scythe Big Shuriken 2 Rev. B Gigabyte GA-H97M-D3H Motherboard (microATX) Intel Core i5 4690S G.Skill Ripjaws X F3-1600C9D-16GXM 16GB Samsung 840 EVO Series 250GB SSD No video card. The TDP of the 'S' CPU is 65W so keeping it cool will not require huge air flows. Water cooling seemed over the top and didn't make things that much easier, I still needed decent air filtering. So, how to do the air filtering? An automotive pod filter. I saw one used in a computer on OCAU years ago and have been keen to try it ever since. This may make this thread a worklog, I leave it to the moderators First, I got some particle board and made a mount using a milling machine with a router bit in it and a hole saw. I painted it black. Next I fitted in a car pod filter mounting part I bought from Repco I think. A fairly small one. The routed out square give the air some space to spread out to the 120mm fan size. I also lets it fit comfortably over the raised honeycomb grill on the side of the case. Just inside the mouth of the shifting spanner there is a hole for an additional fixing screw, a standard wood screw goes through a piece of aluminium flat bar, through the case side and into the particle board. I specially made the particle board mount tall so I could put this screw in for extra strength. It was a good idea, the case sides are quite thin sheet metal and it adds a lot of support. The mount is also held in place by the four fan fixing bolts. Click to view full size! Click to view full size! Fan on with a silicon vibration mount. In this mod it's a seal.

Click to view full size! I powered up the fan and the air flow is very good through the pod. I think even with a slow front exhaust fan and the PSU fan I should still have a case that doesn't suck air in anywhere other than through the filter. If not I will turn off the front exhaust fan (I turned it around, it was originally a filtered intake but the filter was hard to get at and not particularly industrial. There is a shelf under my bench that has some room off the side of it so that the filter can hang off the edge and be entirely out of the way The rest of the build should be unremarkable. Thought this bit was worth sharing. Been a long time since I did any case modding of note. Lots of fun.
