1, some say remove cmos battery for 10 mins before building, some dont mention it ?.
There's absolutely no need to do this as a matter of course.
2. Some mention Raid ? what is it exactly and do i dont i ?
Put it completely out of your head.
3. i will get 6 gig of DDR3 (3x2gig), my MB has 6 slots.. how do i choose which slots to use ?
You'll use 3 slots of the SAME COLOR.. You need to read the manual as to which socket MUST be populated, then the remaining two sticks, go in the same color sockets.
4. is the HD ready to go ? i read on the reviews that you need to format it in windows managment before windows will recognise it ? how can i do this before windows goes in ?
N-O, NO, N-O. When you install Windows the OS drive, (C:/) will be formatted by Windows. The only decision you will need to make is if you want to partition the drive. I suggest 120 to 160 GB for the OS drive. Others will say something else. We're all correct, but I'm more correct than they are.
I have, in the past, changed PSU's, RAM, Optical drives etc and never once thought about static.... have i just been lucky ?
How about if we agree that it wasn't skill.
5. Antistatic ? again some mention it some dont... my house is totally carpeted so how best can i make sure i dont blow up my new bits ?
First, buy an anti-static wristband; Best Buy sells one, (or did), for about 8 bucks. If not, you should hve ordered one with your goodies.
Second; this is the worst time of the year for static. (At least in the northern hemisphere). Cold dry air = lots of static.
Third; keep your pets away from any parts, and an open case. The average cat can kill a full grown computer with one body rub.
Fourth; Find a large piece of cardboard to stand on while you're working. That will stop you from charging up from the carpet.
And finally fifth: Install the PSU first. Then, plug the surge supressor into a grounded outlet . THEN, WITH the SURGE SUPPRESSOR TURNED OFF, plug the PSU into it, put your wristband on and hook it to the case. Make sure you have bare metal on the case under the clip.
As you proceed, continually touch bare metal on the case, each and every time, BEFORE you touch ANY components. Yes, even while you're wearing the wristband. You can't be too careful.
