I have an old Lian Li PC68 case that I'd like to use with a new computer but I'm worried about the cooling. It has three 80mm fans, two intake and one exhaust. Is this enough for a modern computer? If not, are there any easy mods that would make it acceptable (e.g. PCI fan or drive bay fan)? The system will be mostly used for gaming.
These are the parts that I bought and waiting for delivery:
XFX 750W psu
Gigabyte GA-Z77X-UD3H Motherboard
XFX Radeon HD 7950 Double D
Intel i5 3570K
OCZ 128GB SSD
I will also add a hard drive and optical drive
If you're not using many of the optical drive bays you could consider something like a bay cooling kit. It converts 3 of your optical drive bays to an intake fan. There are also converters which allow you to convert the same space so it also take a range of hard drives.
