Will I need to mod my case?

[fsh42na]

I've got a Coolermaster Wave Master. This will house my first A64 system:

DFI Lanparty NF3 250gb
A64 3400+
2x512 mb Crucial Ballistix PC3200
BFG 6800 GT OC video card with Artic Cooler 5 aftermarket cooling
Maxtor 120gb; Seagate 200gb
Liteon 52x CDRW
NEC 3500A dvd burner
Enermax 550 watt power supply

The case came with a solid left side panel. I also ordered a windowed side panel.
I installed the optional top blow hole fan. It came with 2 front intakes and 1 rear exhaust. These are all 80 mm fans.

Do you think I'll need to mod my case by either cutting a hole on the left side panel?

Thanks for your responses

my roomate just dropped his temps over 5C just by putting in a side fan
