Heck NO!
Rule #1. You will always get a big enough case to hold your stuff - BARELY!! If you have an open case, you will find more to stick in there until...
Rule #2. There will be something in the wrong place or layout
Even my Chenbro SR-103 server case is a nightmare to try to rearrange (had to fix some wiring this weekend) w/o pulling it all out. Also ahd to mod the heck out of it to get what I wanted in there in the first place!
Sooo - plans for next case (Rev 3.0 - DIY) are hatching in my mind as I type:
1. Will be height of Desk(nothing goes above it anyway so why not!)
2. Motherboard will sit Horizontal (let heat rise) and blow out back.
3. Rads/pumps will get their own compartment w/ fans at back blowing out.
4. Hard drives in back are good idea, same compartment as MB.
5. PSU may be in same area as MB, gotta figure that out.
6. Question for general discussion: given something like above, should rads / pumps go above or below MB (see good reasons for both setups, want more views).
Got pretty good w/ riveter during last project, plan to make main support structure out of AL angle and sheet for internal air baffles, then enclose whole thing in Oak / Maple (looks nice and deadens sound also). May start a new thread to garner ideas from the intellegent masses....
