i dont know whether ATCS840 is still available or not but im using it with hd6990.

By the way, if u can afford a 6990, why not spend on a big full tower casing? the card is at 12.25" and bulky.

When you casing is small, everything seems to be crowded and air flow will not be that good either.

Anyway, no matter which casing u r getting, make sure u have enough space for the ventilation at the end of the card which has the power connectors. u will not want to get one which is so near to the harddisk rack.

however, the temp of the 6990 at idle is about 48-50C on 27% fan speed and about 80-86C on load, which are pretty good compared to my old 4870x2. If i switch on air cond, it will be even lower.

Haf X is big enough.

Another one u can consider but u have to add a lot more cash for it.

For my case, i would also prefer the casing to have a removable mobo tray for easy maintenance. no need to drag or carry the whole big casing up and down. Perhaps not that frequent but it is real tedious to move the entire casing when it is fully loaded.

yeah, most people are fine without removable tray. Large casing gives u more space to work with, better cable management. however with a removable tray, its even more versatile. i do maintenance and i just have to remove cables, and pull out the mobo tray and put it on a table and continue working.

For a non-removable one, I will have to drag the entire casing, put it on a big table, preferably if i can lay down a layer of padding to avoid scratches and etc. My casing bays are all used up accept for 1 empty hdd tray. So you can imagine how heavy it is, not to mention the bulkiness.

so i will look for a casing with removable tray and maybe some people will disagree with me but the removable tray is one of the deciding factor when i buy a casing. no point spend few hundreds or rm1k and later on regret of not buying another casing due to certain features.

Another factor will be of aluminum construction. it is a must for me.

not only does the fan need to move the air from the front to the rear of the casing, it is also crucial to supply cooler air to the prominent heat zones. so you have to look into the casing and see where are the placements or the fans inside and the sizes supported. So better air flow is more or less resulted from good design and good placement of the fans. Good looking casings are not necessary good casing.

HD6990 exhaust air to the rear and to the front. so u need to make sure u have good air flow to cool down the hdds and lower down the temp infront of the 6990 specially if the 6990 is exhaust duct is pointing towards a hdd rack. the card can get pretty hot on intense gaming.

yeah, it is just how i prefer it to be. if i spend that much of money, i prefer the casing to be more versatile. since i have limited space in my computer room and hard for me to move the entire casing with some many things in the room, a removable tray helps a lot. I dont move it very month but when i want to do something, i would prefer that feature to be available. Anyway, i will be moving to the lian-li which link i posted before. I'm a lian-li fan but was forced to get the ATCS 840 because i got a late reply from the lian-li.

my room is pretty clean but the amount of dust collected at the filters and fan blades are astonishing.

if u have a big room and very sure nobody will disturb or it is real safe to leave it as an "open" rig, then its good.

for me, i don't have the space and i just prefer my casing with a removable tray.
