just an idea. Would it be possible to fit the SFX PSU in the front of the case? there seems to be enough room for it to work. this way we can the full height of the case to use for the CPU heatsink.
Ha! i had that Idea too, I thought about implementing it but In the end, I didn't pursue it because I don't have the tools/equipment.
If you orient it vertically and have the cables pointing up, the fan doing intake from the front fan and the exhaust through the bottom, you will loose alot of airflow from the front fan (not a huge deal) but you'll also lose the 3.5" drive
To replace the front fan, I thought about mounting a 120mm fan towards at the back of the case where the grill is, get a drill and make some more holes, but mount it to the frame of the case cos the case is removeable and may cause cabling issues with a 24pin plug
Theres about 140-150mm height clearence above the CPU so a mid-range tall heatsink may fit the bill, BUT! i have a h55 board so the width kinda sucks.
Fan on the heatsink would be pulling away fromt he heatsink and towards the side fan that I mentioned.
I thought that this setup would lose a lot of ventilation and might get dusty cos out pressure>in pressure.
