--------------------------------

Minor update: Just a few other things, I've picked up; and, a bit of power supply modding. 

The idea is, I want to be able to quickly disconnect the 360 from the loop; and couple the qdc's, in a small loop out and back in. The 360 will just have a loop running in, to the GPU and CPU; and back out, through the watercooling grommets, at the back of the case. I can always just close the loop; when the system is not in use. 
I picked up an OCZ Z550 Series PSU, for a small server; which I intend to design for ultra low power consumption. It's not 80 Plus Gold; but, it'll do for the price. Also, it's a non-modular design; which doesn't work well for me. So.. I'm making it modular; or, at least, cutting off the cables So, I cut off the extra connector's, in uneven length's; and heatshrink wrapped the up, giving plenty of cover. All I left, were the 20-24 pin Main power connector; and the SATA and Straight-Molex Connectors. That should be all I need; for the new home server. 
Finally, I tested all of the connectors; after reassembling the new power supply. Still, maybe a bit more than I need; but, I'll leave that, for later. It's all on the outside of the PSU now, anyway. My test setup, includes a new Antec Digital Power Supply Tester; which, will also come in handy when I decide to leak test my water cooling. After cutting off all those connectors; it still appears to work pretty well.

updated parts list; with current billing info. The watercooling system parts; have almost almost all been purchased. Just missing a few things, here and there
 
edit:
 
Missed a few things in the listing there; its been updated properly now.  

So will I

got my G1/4 Quick disconnects, inline filter, and impingement plates in from Koolance today; and, I'll be picking up some parcels at the post office tomorrow.

Slowly getting all the base parts in; then I have to start--seriously--looking at the case. I'm either not happy with; or not able to use most cases out there. Mountain Mod's would fit; but, I think its a little excessive. Also has to be ordered from MM; as they no longer sell up here. ..I'd want custom anyway.

So, I'm pondering a custom case; and having it prefab'd, for me. ..saves me having to cut aluminum; which, I'd rather not. ..stuff melts to easily. I don't have a real shop; so, a custom fabrication, locally, makes the most sense. All I have to do; is find out the cost. ..working on a design allready; though, not excessively motivated. I've spent to much money allready

This stuff really does cost to much, in retrospect; however, whats done is done, and now I have to finish it. The real waste, would be to give up; with 85% of the build already paid for. Hopefully, I'm over that anyway; with the amount I've spent, to date. (edit: I can dream can't I)

I'll see what I can do about shrinking those pic's; they're a bit cumbersome on the load's. Like wearily drudging through a pigsty; scrolling to the bottom of the page.

Just a few back-ordered items arrived today; almost everything in fact. Still missing the remaining 6 Bitspower fittings; and the Lian Li mDTX case.

Some very cool specialized fittings here. Particularly like the Koolance Inline Flow meter; which, can shutdown my PC if the flow stops. (i.e.: the pump dies; or the system gets a blockage in the flow.)

The flow meter, actually comes in an anti-static bag. I was a little surprised at that; but, understand the logic. It is electronic after all.

..not much of a pic; but I thought I'd add it anyway. It'll be a bit yet; before I start doing any serious assembly; and I don't want to risk contamination, on any of the parts
 
edit: right... picture; almost forgot.. k.. I did forget

okay So, I've recieved permission from my household's ISP; to put a DHCP server on the network, so long as it remains an internal server.

Very cool!

Now.. on with business. I'll be recieving the next bit of stuff to set up this glorious little mITX server; over the next 2 weeks, approximately. I'm not sure how long it'll take really; as, it's been quite some time since I ordered the chassis for this. However, when it does arrive; I'll be sure to post a small set-up and configuration post. shoul be very cool; and look pretty good

I like it

Will also be adding two additional drives; for shared storage later on.

Can't wait to get the build going

Thanks I wish the parts were here.. I'm trying to be patient; but the suspense is killing me

Cool, its new and i like it !!

cool i have a friend that loves to mod xobx360s BTW he is doing one this summer



when you do the xbox you should put it on lamas.com site for xbox moders he is posting his there

Finally got my parts in; the fittings I have been waiting for, and motherboard plus RAM. Been waiting awhile for the fittings; so, I'm glad they finally came. All I need now, is the server and HDD's for it; then I can start that build. Due to the backorder taking an inordinate amount of time; I am changing to a slightly pricier chassis. The Lian Li VM351I; which is actually blue. Which is allright, because the board and RAM are too; though, I hadn't counted on that when I made the purchase. So losing out on the lengthy back-ordered red chassis; isn't so bad afterall, and I think the build will be nicer without it.
 
One small pic

You can find the worklog, for the DHCP server here. This thread will continue with my gaming rig build later; as I get parts in, and start to mod and/or build. I'll probably post briefly, regarding the completed network later; once I have it entirely set up, and running to my satisfaction.

Have had a few modification's to the build list; and overall plan, for this build log. See edited posts regarding the components; and the main entry above, for that.

Aside from that, the HTPC seems to be running stable; with the new configuration. Running Linux Mint 8 on it; and that has been an experience. I'm still a Window's man; haven't really got the draw for Linux based operating systems. They are interesting, and useful, in there own way; but, far to complicated and user intensive, to be truly enjoyable. The file structure is monstrous.

I have attempted to install the DHCP server; however, it failed for unknown reasons. Likely, due to my not having installed libraries; of which, it is dependent on. I have no idea what these are at the moment, and the repositories contain some 29K plus packages to search through; which means I am not going to bother looking until I know for certain, what I am supposed to be installing.

Lot's of fun..
