Making of Mach3, lots of pics

This whole project started when I saw a brand new AC condenser on e-bays for just £10, I eventually got it for £21 after the bidding and P&P. I already had some scrap metal which I got from a skip so I got to work. Firstly I measured and cut the pieces for the frame.

Now the pieces had to be welded together.

Then I cleaned it up with an angle grinder.

The frame is very strong, I tested it by standing on it!

Next the pump, after speaking to you guys here I decided to go for a more powerful pump, the Hydor L30 because I already had the fittings for it from my old L20 and it's alot cheaper than the Eheim 1250. Using these pumps out of water shortens their life due to the lack of cooling so I strapped some fans on it, now its cool to touch.

The radiator is MASSIVE 23cm X 31cm X 5cm, I had to braze on some 8mm copper piping to adapt it for my compression fittings.

Now I had to make a shroud to get the most out of this rad. I made a template out of card first and tested it for size, then I just traced around it on some scrap sheet metal I found.

Welded together and painted black.

At around this time the panels were ready. I had given the designs to a friend of mine who got them made at his work place, cheers Taz.

The panels where very shiny...

...so I had to try and dull them down a bit and try to get a brushed aluminium effect. I rubbed them down with some scotch brite, still needs work here in this area.

Now for the reservoir. I had some acrylic cut to size to make a side panel res. Checking for size before sealing with silicon.

Sealed with silicon.

At about this time I got my block for my 6800 Ultra from Germany, thanks to Andreas V. for being really helpful.

Fitting all the bits in...

At this point it's worth mentioning DONT RUSH. Well that's what I did, I filled the reservoir after 24 hours only instead of 48...

...the silicon started to dissolve as its had not fully cured. So I had to drain the whole system and take the reservoir to bits. It took six hours to clean all the silicon of properly :mad: I resealed everything again and now I'm just waiting...

Still needs some work to get the panels matching properly, any ideas anyone? I've run it a couple of times using a tub as the reservoir and everything seems fine. Just need Phil to get some Crystalfontz 3.5" Lcds in now to finish it of ;)

Awesome, although what size tubing is that?
Cheers guys, the tubing is 3/8". The past couple of days have been the hardest, having to just wait for the silicon sealant to cure but today I couldn't stand the waiting anymore so I hooked everything up and filled it up. I'm getting 466/1.24 on the BFG 6800 Ultra OC. I havent tried flashing it yet. Phil, need some info please mate, I heard you flashed yours with some good results, which bios did you use and where did you get it from? Thanks.

Mine is at 491/1310 - taking some serious cooling though, the side panel is off and there is a 120mm fan blowing over the block, I'm also using 1/2" tubing which offers a faster flow rate than 3/8.

The Bios is here:

www.extremeprometeia.com/6800bios.zip

Extract files, run

Nvlfash -b backup.rom (to backup your current bios)

Nvflash -5 -6 XFXUltra.ROM

ps I'm not responsible if anything goes wrong! Use at your own risk.
 
Well I flashed the card and tried both bioses. I got better results with the 450/1200 version.

Core: 474 Mhz Memory: 1.3 Ghz

Idle temp: 54 c Loaded: 64 c

3DMark2003: 13672

3DMark2001SE: 23111

Aquamark: 75293

Thanks Phil for the info, I've seen many bioses on other forums and alot of claims from different people but I wanted something from someone I could trust, cheers mate.

I think I'll leave it at this now before I stuff it up!
 
Thats pretty cool :D

Hope you dont live in earthquake country and watch out for those low flying air craft ;)

i got me a BFG 68U runs 450/1240 air cooled, havent done anything to it yet its running about 60C at full, and 50 idle, no artifacting. I would like to try the volt mod bios.

very nice m8.

So when you going into production of these m8 :p

Id buy 1 off ya ;)

You don't want to know how many hours I spent on this thing mate but find a company to make the various bits and we're off.
 
excellent job zax, truely was a pleasure reading your article, matching the colour up is gonna be impossible i think unless u get the whole lot re-anodised which will cost a fortune !

Thanks Axer. I got a really good quote on anodising the whole thing black, £120.
 
EP UKs Modfather.

Excellent work!! Best Modded case I've seen on EP UK yet. Very informative post on how you put it all together. As suggested it would probably be best to get all panels re-done in a finish of your choice.

Truely innovative, will be interested to see your next project.

PS Why not post on Custom PCs readers drives? I think you stand a very good chance.

Happy modding.

Great price Zax, i would definately go for that, it will look fantastic!
 
OK, I've finally managed to get my hands on a 3.5" Crystalfontz LCD display unit, these things are mad. I've made various screens to monitor my Vcore, FPS, E-mails and loads more! Phil, if you read this, you really should get some of these in stock. Here's some pics...
