Ok, I'm about to start building my newest system (when the case arrives, that is) and I think I encountered a problem that some creative modding may take care of, so I need some opinions. I ordered a Thermaltake Tsunami case (which is listed as an extended ATX form factor) and a Tyan Thunder K8W Dual-Opteron MB (also listed as extended ATX form factor), but the more that I examine the internal case pics online the more I think that I am going to have a bit of a clearance issue. If I'm correct, the DIMMs and Heatsink/Fan for the second Opteron are not going to clear some of the drive bays. So here's what I'm thinking: Cut out a section of the bottom (unused) 5.25" bay, Remove the External 3.5" cage completely, and cut a small section out of the top (unused) Internal 3.5" bay. That should take care of the problem, but is there anything that I should know or be careful of before attempting this? Any suggestions?
