**UPDATE** 05/05/11
Following some extra tips/advice garnered from here, I've decided to do most of the case modz myself.
I'll ensure I update this thread (along with the OCAU one) once progress is underway...
The primary focus remains modding the case, selecting filtration medium, & building a wooden filtration box.
LT I'll design/build a fancier filtration box, but I've opted for a simpler route for now, much more detail soon.
***********************
This is what I've garnered so far as the options for PC air filtration:
*air cleaning/purifying filters
*air conditioner filters
*dryer sheets (fabric softener sheets)
Much less resistance, but also much poorer filtration:
*DEMCifllex
*pantyhose (nylon stockings)
This is a very good read, some quite clued-up users there!
Alas it seems skinnee hasn't done any detailed comparisons (that I see) between filtration mediums
Is anyone aware of any detailed/methodical comparisons?
My case is a black Silverstone CW02, it's still approx. 3weeks away from arriving.
I'll be modding the 2x 92mm intakes on it's base to 120mm...
And cutting an extra 120mm exhaust on the rear of the case lid, in line with the PCI/e slots.
I'll also be fashioning a mounting bracket for my H20-220 edge (AIO rad/res/pump from swifttech)
This mechanism will be bolted to the back right corner of the case lid, near the water tube holes.
The H20-220 Edge will have 4x GT AP-15* in P+P (possibly w/shrouds, YTD)
For the 2x intakes I was going to use 2x AP-14 (1450RPM)...
I was going to use 1x AP-15 for the exhaust on the lid (can undervolt), & 1x AP-14 for the other.
Or to be sure of +ve pressure, maybe I should use 2x AP-15 for the intakes, & 2x AP-14 for the exhaust?
Especially considering I'd be using filtration material on only the intakes.
One needn't dramatically reduce fan airflow with a high resistance (superior) filter medium.
One can get around the problem of resistance by greatly increasing the filter medium's surface area.
You do this & a standard (quiet) case fan's capacity to move air is no longer dramatically limited.
Subsequently I'm contemplating designing & building a filtration box to sit under my CW02.
I've been inspired by that google groups thread I read above, and this guy's handy work.
However I'd like to do something a bit less "ghetto-ish"... no offense dasa
It'd be all aluminum, but it needn't be brushed/sandblasted & then anodised, like the black/silver cw02.
The idea so far is that it'd be designed to sit under, & look like it's part of, my cw02.
It will be approximately 12cm in height, plus the same depth & width as the cw02.
The sides, back, & base of this filtration box will be non-existent, filter medium will be seated there.
It will prolly have an aluminum facade on the front, just so it looks more like a part of the cw02.
But I will design it such that this facade is removable, and more filtration medium addable.
Extending from it's top will be 2x Alu shrouds** that align perfectly with the CW02's intake vents.
An alternative concept I have in mind...
Is a funnel that encompasses the 2x vents, & then narrows to 1x 140mm intake at the filter box's centre.
This avoids having 2x intake vents right near the left & right sides of the filtration box, not optimal IMO.
Apart from dasa (thanks for the inspiration), has anyone heard of others doing something like this?
Perhaps there are pre-fabbed solutions out there?
If not, any thoughts on design approach & the best performing filter mediums are greatly appreciated!
Thoughts on design/build approach in particular, as I've no experience in this area & no suitable tools.
So I may have to come-up with a rough design, and then get someone else to fab. it.
Thank-you!
*This range of fans are universally lauded nowadays for having excellent noise to cfm ratio.
Whilst maintaining decent static pressure...
**Roughly the same height as the CW02's feet, or feet height + rack-shelf thickness.
