I would recomend you install your HDD (bottom cage) & DVD's in the case first after you have removed all the side panels.
Next, decide if you are going to install the inside extra cage fan or not... Install or next step....
Route your case power button/ USB wires through the opening at the top to the back of the case... Repeat the same for the fan wires.
Next, start on your MOBO.... Install CPU then heatsink using a pea size of themal paste (think size of the end of a pen) then I stall your RAM (all outside of case) Now you are ready to install in the case.
install the rear I/O panel sheild then place the mobo in the case to see where the mobo mounting screws go on the case. Remove the mobo and install the mounting screws into the case where they lined up with the mobo.
Install the mobo (remember my comment from your previous thread about this) and screw the mobo in to the case.
Connect your SATA drive cables & case power button / USB / ESATA to the mobo.
Install PSU next and hook everthing up... Remember you cable management while doing these steps.
Last install you GPU's and hook them up
The rest is yours! . (I hope all that made sense to you & answered your questions)
Hey Tecmo! Success! Your suggestions were a huge help, thanks a BUNCH. My only disappointment was when I opened the second GTX260, it had this weird all-black case, not the red along the edge. Turns out it's a slightly older/slower version, but still the 55nm so I'm good. I posted a question about it in the EVGA forums, and got advice on a utility to run, did that, and got my answer. Figures that Dell would send me old stock, but it was only $113 after codes and rebates so I can't complain (and $9 for tax also).
Installing my Adobe stuff now, hope to get Flight Sim X going soon. BTW, I'm not done with this rig, I still need two 1TB HDs for video files (in RAID). That can wait for now, have to pay off the Mobo.
You are welcome!! Glad I could help & the build went smoothly for you!
