yea i like my sg01 a lot,
hmm thats the bad side to most sff cases there
aint much room for cooling. becuz the psu sits on top where the HFS is
most of the HSF you can use need to be about 85mm (8.5cm) in height
here is a list that should fit but some might not. as some might need modding
or cant fit becuz mother board parts might be in the way ( ie ram pci slots + more)
Zalman CNPS7500
Zalman CNPS750
Zalman CNPS8000
Zalman CNPS8700 LED
Zalman CNPS8700-NT
Thermaltake Blue Orb II
Thermaltake Golden Orb II
CoolerMaster Gemin II ( psu blow fan cooled )
Silverstone SST-NT06 Lite ( psu blow fan cooled )
all stock HSF fill be it AMD or Intel
here is some pics of my sff setup
