This may be the neatest thread I have ever seen! Great work, I am in awe :D And I love that you added the cute kittens
Thanks liddabit! I'll try to add some more kitten pictures in the near future lol!

starting to get into the nitty gritty!

looking good
Thanks Zargon - yup - the fun part is just about to begin! (Not that the woodworking wasn't fun... but you know... PC hardware!)

If you need help with any PC part selection or advise head over to general hardware :p
I'll keep that in mind! I don't think there'll be a problem with selection... it'll be a problem of budget lol!!

Sorry for the delay in updates everyone - I've been enjoying the beautiful summer weather we've been getting lately and haven't been putting a tremendous effort into getting the desk finished.

Surprise though - I did manage to get quite a bit done, and I've had some good fortune lately as well. I expect to post several updates this week, so just to get you back into the spirit of things, here's this weeks preview!

4x Scythe Ultra Kaze 120mm x 38mm 3000RPM
4x Scythe Slipstream 120mm x 25mm 1900RPM

Lots of foam cutting and trimming, and a sweet, sweet ruler from the Moddders Inc Featured Rig of the Month Contest(Thanks! I'm honored!)
img6262z.jpg


Hmm, what's this?
img6263eo.jpg


Holy moly cool prize pack Modders Inc! I still can't believe I won this - perfect stuff for The Ultimate Computer Desk!
img6267w.jpg


Finally removed the protective cover from these babies - they look soo nice!
img6319j.jpg


Hmm? Another surprise?...
img6320j.jpg


Oh good lord! What kind of super monster is that!!?
img6340m.jpg


Bwahahaha
img6359o.jpg


Ok, so maybe a lot's happened in the past couple weeks. I haven't been posting any updates because I've been tinkering around with hardware AND enjoying some good outdoor times. I'm thinking that the next round of updates in the following month or so will be ultra exciting - things are starting to wrap up!

Seeya soon!

Looking good. Congrats on the monitor; I'm looking at the same one to replace my 20" Viewsonic. BTW what kind of keyboard is that?

now we are talking!!!
Yeaaaaaahhhhh!

Thanks! The keyboard is a Thermaltake Challenger Ultimate if I'm not mistaken. I'll be doing a small write-up about it shortly!

After gluing a few blocks of foam together with a spray adhesive, I trimmed the block down to the appropriate size using a bandsaw.

img6270e.jpg


Unfortunately, it wouldn't fit in order to do the vertical cut...

img6274q.jpg


So I took out the trusty hand saw!

img6275e.jpg


img6279g.jpg


Here's the plan for the fan layout

img6280a.jpg


img6281z.jpg


At first I tried cutting the holes with a good quality knife, but the cuts were not very consistent and it took a long time. I ended up using an old drywall saw, which worked perfectly.

img6284m.jpg


Test fit

img6286p.jpg


Cut some more holes

img6288y.jpg


Awesome!

Let's see how it looks in the right-hand cabinet

img6291r.jpg


LOL - hilarious. It shouldn't fit like that. At least, it didn't during my initial measurements! I'll have to tweak that a bit later!

On to the crazy fans. I decided to go with 3 instead of 4. There just wasn't enough room for foam between each of the fans, and I figured there would be a lot of vibrational noise if they were touching. I could always go to 4 in the future if this proves to be insufficient.

img6293o.jpg


Lookin good

Stay tuned! More stuff tomorrow!

Absolutely! I don't always reply, but always look.
Heh, thanks Zap!

those fans will move ALOT of air
Sure will! Hopefully they will push enough air that I will not need to make any exhaust fans... Only experimentation will tell at this point unfortunately!

Makes me wish i didnt have all these college fees to pay.
I hear ya! I'm still paying off my college stuff actually... which probably contributed to why I've been working on this project for almost 10 months now instead of 3 lol!

I was in an extremely fortunate position recently. A friend of mine's work was moving from a large location to a much smaller location, and he had asked me if I wanted to come scope out the old office for any old bits of computer stuff that might be useful to me. To my shock and amazement, I was indeed able to pick up some pretty fancy hardware that I would have never dreamed of owning. They must have done some pretty big upgrades to leave stuff like this behind!

I was able to get a hold of a handful of Socket 775 motherboards with Core 2 Duo processors, a bunch of DDR RAM, a box full of Hard Drives, and some relatively decent (lower powered) power supplies. The real treasure though, was a pair of servers. You can see that I had already disassembled one of them:

img6301l.jpg


2 Full 4U Antec Rackmount cases, each of them containing a Dual-Xeon motherboard + Processors. Both with FB-DIMM RAM sticks as well.

This particular one contained a pair of Xeon E5410's, with 16GB of DDR2 FB-DIMM's, 4 1TB Western Digital Blacks (SATA), and the motherboard is an Asus DSBF-DE.

img6302t.jpg


The other one contained a pair of Xeon E5335's, with 4GB of DDR2 FB-DIMM's, 5 1TB Hitachi Deskstas (SATA), and the motherboard is an Asus DSGC-DW.

Now - before we go on - someone had queried earlier about the PCI Express slot on the board pictured, and I had said something along the lines of "Ya ya, it's there, don't worry about it". I of course, actually looked at the pictures, and no, it's not. It is indeed a PCI Express 16x slot, but on this particular motherboard, it only runs at PCI8. Now, the other motherboard, the Asus DSGC-DW DOES have a PCIX16 slot. When it was released, it did not support the 54xx series of Xeon processors, but I checked the website and there is a BIOS update to add this functionality. I will have to do a test setup with that board to update the BIOS, and then it will be swapped into the desk with a full video card, both the E5410's, as well as the 16GB of RAM, so keep that in mind when looking at the rest of this update. No, unfortunately, I didn't take any pictures of the other motherboard.

Cool stuff either way. Never, ever thought I'd have a dual processor motherboard. What an amazing find!

These dual Xeon heatsinks mount directly into the motherboard tray, so unfortunately, I couldn't use those spiffy motherboard trays from Danger Den. Also, since they are of size "SSI", there's no way it would mount on a regular ATX motherboard tray anyways. Time to drill out a tray!

img6305qz.jpg


It actually came out pretty nice and clean

img6306u.jpg


This is a bit of a shame, since I took the time to clean the processors, put new thermal compound and remount everything. I'm just going to have to disassemble it again anyways when I put in the different motherboard. Ah well.

img6343d.jpg


img6358m.jpg


This is a bit of a hack job getting the tray mounted... Since the processors are mounted to the tray, I had mounted it outside of the desk, so when I went to fasten the tray to the desk, I was *gasp* actually lazy and didn't want to dismount the motherboard again... so umm.. I'm going to replace those odd-angled screws when I switch motherboards..

img6362t.jpg


The power supply looks pretty good there. It's an Antec 650W - an Earthwatts maybe? I forget. I may consider replacing it with a unit that has a 120-140mm fan just to exhaust the air a bit better. The board has a requirement for a 24pin, an 8pin, as well as a 4pin, so I can't just use any power supply unfortunately.

img6364c.jpg


The cables, of course, are not nearly long enough to reach the connectors on the board. I've already ordered the extensions and hopefully I'll get them at the beginning of next week. Oh, you'll see that I've straightened out the fans as well.

img6367br.jpg


The cooling solution looks good. There will be two fans directly in front of the CPU's. I may consider putting an additional hole in the door to allow the CPU's and RAM to exhaust directly.

img6370a.jpg


There is one major issue with the right-hand cabinet setup. The original specifications called for an ATX board, which is significantly smaller, so umm.. I have no idea where the hard-drives are going to fit. lol! Fun times.

Hope you're enjoying this flurry of updates. I may or may not be able to post an update tomorrow, as I'm going camping for the weekend! At the latest, I'll be posting again early next week!

is there space in between the PSU and the fan to mount the drive cage out of the server?

Thanks for the comments everyone - yes - what an amazing haul, I am still counting my blessings for that one coming in at such a perfect time as well. Better than them being in the trash, that's for sure!

As far as the HDD positioning, I am still working on that...

A huge thanks goes out to Gigabyte for supplying me with this amazing motherboard - a GA-Z68XUD4-B3.

Without a doubt, the coolest motherboard I have ever owned!

img6309t.jpg


I could barely wait to open this up when I got it in the mail!

img6310d.jpg


img6317j.jpg


And this poor motherboard tray that had been sitting for months and months covered in brown paper - finally had it removed. It looks even better than I could have hoped!

img6322lm.jpg


Here is the test fit in the actual desk

img6328.jpg


And with the fans in place

img6329kl.jpg


I'm going to trim off the plastic tabs from the motherboard tray to make it a bit easier to build the tunnels for cable management. Also, I'm considering putting a pair of holes beneath the motherboard to pass cables through underneath. Lots of stuff happening in the next few weeks!

I attempted to boot up the Asus DSGC-DW board (The one with the PCIx16 slot) but it would not boot. I'm afraid that that particular motherboard has gone bad, so I will continue to use the board with the PCIx8 slot. Anyone have any suggestions with regards to determining the best video card I can put in a PCIx16 slot with only x8 bandwidth? I was thinking I could look at the theoretical bandwith of an 8x slot and match it with that of the video card to maximize performance (ie. no point in installing a 5970x2 in an x8 slot).

Anyways, hopefully will have a handful of updates this week!

nice!

too bad I had already bought a rackmount chasis before your last post, I'd a bought one of those antecs off you instead :p

Almost all current GPU's will not be bottle necked severely (besides HD5970, HD6990, and GTX590) so feel free to put in an HD 6950 or GTX 570. You will still be somewhat bottle necked but i think anything over that will really start to hurt.

Hehe, seems as though the Antecs are real commodities! Wish I had known beforehand!

Thanks mnewsham, that's pretty much the info I came up with as well.. it's pretty rare to lose more than a few percentage's in performance with only an x8 slot

So - it's been another few busy weeks, so apologies for the no updates. Have been enjoying those last rays of sunshine before the summer ends!

I think I mentioned last update that I tried to boot up the Asus DSFC-DW board but had issues - here was the attempt:

img6371l.jpg


img6373a.jpg


I got a green LED to light up (Standby power on the motherboard) but jumping the Power ON pins had no reaction whatsoever. Tried it with a different videocard, re-seated the RAM and CPU's, but still no luck.

Moving onwards - since I un-mounted almost everything, I decided to keep the copper heatinks instead of the aluminum ones for the other motherboard. I also picked up a pair of these units from Rosewill via Newegg:

img6374u.jpg


img6375z.jpg


They should do nicely for my hard-drive racks. I would like to mount them like so, except higher up:

img6376bv.jpg


Unfortunately, they are deeper than the cabinet I built. At the time, I was thinking maybe they would stick out of my air intake window, and I would just build-out the section of the door with the air filter... Not exactly what I had in mind initially though.

With most of the major components in place, I decided to start tackling the cable management with some cardboard templates, and then some 1/8" plywood:

img6380k.jpg


img6382rl.jpg


img6384t.jpg


At this point I was a little frustrated with how slowly this portion of the project was going. Things weren't quite fitting the way I had planned, and they were not looking as nice as I would have liked them to...

Maybe it's time for some thinking instead of doing.

I decided (In hindsight, unfortunately) to go ahead and mount the hard-drive racks so I could get some better measurements and ideas of how to manage the cables nicely.

img6399t.jpg


img6402g.jpg


Installed the fans and started to route some of the cables

img6404sa.jpg


Took out a handful of old SATA cables... (Yes, let's not forget, that I'm a computer tech first, and a carpenter second, or maybe even fifth or tenth...)

img6405s.jpg


And had fun connecting all the bits and trying to get them in a reasonable state of organization

img6409a.jpg


img6411f.jpg


img6412s.jpg


Ugh... this will not do, this will not do at all. Might as well boot it up and see if everything works though (I had mounted and un-mounted the board several times, banged around a few things, etc, so might as well see if it's all still working!)

This would be the first time I see if all the fans work as well. Keep in mind that this is with the door removed.

img6414gt.jpg


Until next time.. still not quite sure what I'll be doing next.

needz more cables :p

looks like a spider is moving in!
lol thanks Zargon, seriously eh? That's what sort of prompted me to start from scratch below...

First off I want to give out a huge thank you to Seasonic, who has decided to sponsor The Ultimate Computer Desk by sending a ~really~ sweet Power Supply my way. An 850 Watt Seasonic Gold.

img6422m.jpg

seasoniclogo.gif


Thanks Seasonic! We'll take a closer look at that PSU a bit later..

I had been a little frustrated with the layout of the Dual CPU Xeon board for quite some time, so I finally made the decision to ditch it and setup the right-hand cabinet with an ATX sized board. This is more in spec with my initial design - the extra couple inches makes a big difference, and it will make it easier to upgrade in the future as well.

On one hand, I'm a little disappointed that I won't be using that super geeked out board, but rest assured, I'll find something else neat to do with it.

So I went ahead and removed everything and started from scratch. Looks way better already:

img6427.jpg


img6430i.jpg


I then decided that, unfortunately, through the miracle of cable limitations, it would make a lot more sense if I put the optical drive in the front of the case, as opposed to up above the desk, where I had originally wanted to put it. So, time to do some more cutting.

img6436b.jpg


img6435k.jpg


The masking tape managed to pull off some of the polyurethane, but have no fear, I will be making a faceplate that will contain the power button, LED's, and USB ports that will cover that spot up quite nicely.

img6443q.jpg


And, we've gone so far, yet, gained so little, eh? It'll get done, I swear!

An amazing job done so far. I've always wanted to try my hand at a project like this, but don't have the patience (or skills :p)

Looking forward to the next update
