I got the majority of parts today (albeit, missed a day of work waiting for the delivery... ). The slot-loading DVD drive is still MIA, but I have the rest.

The PSU is installed to the case.

Well, there's a chance we'll get that update.

I'd install everything I could onto the motherboard before installing in the case, but the last heatsink I put on took a huge amount of pressure to get it to snap on, so it needed support underneath, not possible when in the case.

The motherboard is secured (8/9) to the case.

The think I stripped the first standoff and was unable to get the good 8 screws out to replace it so I'm just leaving it as is. It seems secure... I had to apply some pressure to the motherboard to push it towards the back (i.e., towards the IO panel) to get it to line up with the holes.

I don't think it works that way.

I typically install the motherboard into the case, then put the cpu in the socket, then put the heatsink on the cpu+motherboard. Since the heatsink physically/mechanically attaches to the motherboard you have to install the cpu into the motherboard first.

Though you can install the cpu and heatsink before installing the motherboard, but I don't like doing that, you have to find a nice flat clean surface that you don't mind marking up with tiny dots from the rear of the board.

Installed the CPU cooler (heatsink/fan).
Installed the RAM.

The RAM slots of this board are a bit interesting. Only one side has clips that work.

(Confirmed by this site; picture theirs)

I was pushing really hard on the one side nearly cutting my fingers, and even started pushing with a screwdriver (at Kazmirr's advice ) before I decided to consult the mobo manual (and then the Web to find a picture to show IRC). I somewhat damaged the non-functional left-clip of the first port (from the bottom), but I don't think I hurt anything (since it isn't even functional). Sigh...

Append:

I think I have all of the power connections done (except for PCI-E as I haven't installed the GPU yet).

Powered it up to test and everything seems happy. No beeps^[1] or angry signs. All the fans are working, including the CPU cooler. It is, however, a mess of cables in there right now. I'm not really sure how to manage them (this is probably the one thing that scares me most about building your own PC). I might have to remove all of the cables and do it over again to make them fit nicely so they're tucked out of the way of the CPU heatsink and all the fans and such. I don't look forward to that. I'm too tired to continue (if I do there's an even greater chance that I'll fuck something up) so I've tucked the loose cables back into the case and put the side cover back on it (and unplugged the power cable AKA ground AKA my anti-static strap... ).

It's fine to take more time, read the manual and anxiously double check everything, when you're inexperienced. Though, you should try to finish as soon as possible.
As for the wiring, you might find that when redoing it, it will go easier. Of course, you'll want to leave the mobo power cable in place. If you're getting confused as to how to prevent a cable mess, 'roll up' all the cables and only look at the connectors. When ready you could also go for a tie-wrap or something to hold some cables together/shorten them.

According to that site you mentioned, it does work. It just doesn't move :p

Maybe that makes me simple.. But it generally takes me a good 30-60 minutes to assemble a machine from scratch. More (two hours, ish) if I have to take it apart and clean it before (re)building it.

I can build a computer, disassemble it, and put it back together in less than thirty seconds.

It usually takes me an hour. Then again, I'm really anal about wires being neat, static charge, dropping things, scratching things, etc.

From the sounds of it, things are going relatively smoothly for a n00b who never read the instructions. Probably saved a lot of money and I guess learned a lot too.

I did read most of the instructions. I got bored eventually though and started skimming for what I needed right away. Did I miss anything?

SSD installed.
HDD installed.
GPU installed.

All that's left now is for my (MIA) DVD drive to be installed and I should hopefully be able to put my current PC out of service (or make a second Linux box or something). I've run the system now with video and all seems well (both before the GPU was installed and after, using the GPU's video ports). So I'm confident that it will run. I've done a poor man's job of tucking cables in for now that I think will suffice. Nothing is (or was) touching the CPU cooler anyway. It would probably benefit from a more organized approach, but I'm not really sure how to accomplish it. The case did come with a number of ties though for just such occasion.

I discovered that the MB supports "Express Gate" AKA Splashtop, which is basically a minimalist OS provided by the motherboard for basic Web browsing and file access and such. However, it apparently requires you to run an installation CD from Windows to use it. WTF?! Ugh. Anyway, I'll see what is involved. If I can install it purely to the motherboard then I might try it just to see (might come in handy for recovery or something). Otherwise, it seems like a complete waste of money (I'm not going to bother installing it to the hard drive if it comes to that).

Append: I should note that I had some trouble screwing the SSD into the drive bay. It's a 2 1/2" SSD that comes with a 3 1/2" adapter. Very few instructions come with it so I had to wing it (how hard can it be?). I initially screwed the SSD into the adapter backwards, which I discovered when the holes didn't line up in the case's drive bay. Once I fixed that, I couldn't get the screws through the adapter. Turns out the holes are just too tight and won't take them. I managed to get one front screw firmly in and the other front screw "in" (it still turns and doesn't tighten up so it's either stripped or just ... I don't know, it doesn't quite make sense). In any case, it shouldn't go anywhere, and with no moving parts a loose fit shouldn't hurt any... I was semi-tempted to drill (and tap?) out the holes, but the difference has to be so microscopic that I'm unlikely to guess the correct bit without knowing exactly what the inside diameter should be...

It's certainly possible, but I don't think it's supported by Microsoft. Moreso, IIRC from the last time I installed Windows 7, Windows 7's disk partitioner sucks ass so I'll probably be using a Linux LiveCD to partition my drives before installing so there's space for Linux.

My case has all 5 1/2" drive bays with 3 1/2" adapter bays. It includes custom screws about 1" long (approximate) to accommodate this. My 500 GB HDD fit these screws beautifully. The SSD's 3 1/2" adapter did not. I can't use the screws that came with the SSD because they aren't nearly long enough to actually reach the SSD adapter.
