I hate to say this but 90 does seem high untill you ask yourself.
Just how long will I have this case?
I had the Enlight for 6 years and was happy untill I finally decided I need a new case.
The Enlight went from an K6 200 to an Athlon 850 about 6 different configurations.
I say this in hope you will consider my suggestions.
This is only an opinion and I will give you 2 cents.
Chieftec 1030 White
Chieftec Black
The best thing about this case is ROOM.
Cooling is top notch as there are 4 places for fans of 80mm and 1 of these is inside the Hard drive bay(instant HD cooler for up to 3 drives.)
Also the side is so easy to remove you will wonder why this is not standard practice.
The fans snap is so easy you will wonder why they ever used screws.
The Drive raill system is also very nice as are the internal bays.
The price however is 102.00 shipped.
Did I mention this case is heavy?
Just a great review
