if going for Raven RV01 then i suggest you upgrade the stock fan to FM181, it made lots of difference to me.

also the sliding door do posed some problem after sometimes of pulling coz the locking mechanism on the bottom will be worn out

not sure about RV02, but someone said the motherboard tray has smaller space so it has a higher intake air pressure towards the motherboard which translates to better cooling

go google Silverstone RV01 vs RV02
