I have had the same tired case for a while. Here is what I have under the current hood (I know it is kind of weak but I am not really a gamer):

EPoX EP-9NPA7I 939 NVIDIA nForce4 4X ATX AMD Motherboard
ZALMAN ZM-NB47J Aluminum Heatsinks only
3D Fuzion 3DFR66256X GeForce 6600 256MB 128-bit DDR PCI Express x16 SLI Supported Video Card
G.SKILL Value 2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 400 (PC 3200) Desktop Memory Model F1-3200PHU2-2GBNT (plus another .62 G of old memory)
AMD Athlon 64 3700+ San Diego 2.2GHz 1MB L2 Cache Socket 939 Single-Core Processor
Surepower 430W btx/atx 12v
40 G hard drive
200 G hard drive
Windows XP home service 3

I have run out of space in the current tower and would like to go to a new one. I dont want to spend a ton of cash but would like something I can grow with.

What do y'all recommend?

Many thanks in advance.
