Overclocked Orange
Overclocked Orange by Mremulator
Foreword, by Antony Leather
David Penfold or Mremulator as he’s more widely known on various forums, was inspired by last year’s Custom PC Dream PC labs test winner - The Great White, entered by Scan.co.uk. While it used the same Silverstone TJ-07 case, David’s Overclocked Orange took on a very different form early on but also boasted a monster specification once he’d finished it.
After a considerable amount of deliberation on the name and components, Overclocked Orange takes its name from the book, A Clockwork Orange and the theme features heavily in the build. The attention to detail is staggering as is the whole PC. In fact he even had the BBC knocking on the door wanting to video it! You can see the video here but read on for an insight into how Overclocked Orange came in to being. Without further ado, it’s over to David.
Introduction and conception
I was reading Issue 61 of Custom PC magazine on holiday last summer, when I came across the annual Dream PC labs test. The winner was Scan’s Great White Dream PC and I knew then and there that I’d love to build a similar PC.

The SilverStone TJ07 case has always struck me as a beautiful thing to behold and the fact you can fit triple radiators in the top and bottom meant it was well suited to my needs. Given that it had also received glowing reviews, it seemed to be the logical choice. I’d seen other modders powder-coat cases in orange and black, and thought this colour combination was amazing for a PC case.
With both a case and colour scheme in mind, I needed to think of a name for the project. The inspiration for this came during a drive home from work. Names such as Orange Dream Machine, Tangerine Dream and Orange Extreme ran through my head, and eventually, I thought of the film ‘Clockwork Orange’, and finally decided on Overclocked Orange.
Neat and Tidy
Having built a few water-cooled PCs before, my first priority was to achieve a clean, uncluttered look. I decided to use PrimoChill PrimoFlex PRO LRT tubing, since you can bend it a lot without it kinking and therefore avoid killing the flow rate. To match the colour theme of the case, I decided on black hosing with UV orange anti-kink coil springs.
I also wanted to set up two separate water-cooling loops, each with its own triple 120mm radiator. I decided to use 1/2in internal diameter hose for the loop that cooled the CPU, and 3/8in internal diameter hose for the GPU loop to differentiate between the two loops.
I initially wanted to use completely new hardware for Overclocked Orange, but I already had three GeForce GTX 280s in my existing rig and various other components that I decided to put to good use combined with some new Aqua Computer full cover water blocks. I decided to order some Bitzpower 90 degree fittings from Sidewinder Computers in the US which would look great when all three graphics cards are connected together.
When I first started the project, I knew that the launch of Core i7 processors was imminent, so I waited for a while and bought an Asus Rampage II Extreme motherboard, Core i7-940 chip and 6GB of 1,600MHz Corsair DDR3 memory. I wanted to water-cool the motherboard too, even though the X58 chipset runs fairly cool due to the memory controller now being integrated into the CPU. I decided to wait for the water-cooling hardware manufacturer Bitspower to release its greatly anticipated chipset block which arrived recently. It was worth the wait!
I was a little disappointed with the finish on the main block so decided to modify it slightly. After a bit of polishing, it looked much better! When I bought the case, I had it modified to make the build easier. I asked WCUK to cut a hole in the motherboard tray so that I could remove the backplate from the CPU water block without also having to remove the motherboard.
Start your Dremels…
WCUK also enlarged one of the rectangular holes in the base of the main compartment to allow the hoses from the pumps to pass through it easily. The standard vent in the roof which accommodates two 120mm fans was then enlarged to accommodate a Black Ice Stealth 360 radiator and grille.
To control the fans, I used a Rheobus fan controller, which was powder-coated black. I replaced the red/blue LEDs in the controller (and those throughout the case) with orange LEDs.
The outside of the SilverStone TJ07 was powder-coated bright orange, with the inside and the drive bay covers a glossy black. You need to dismantle the entire case into different sections to do this.
Artwork
Part of what makes Overclocked Orange a little different from most water-cooled PCs is the artwork. Thanks go to Solphorinc from the Chilled PC forums who kindly helped me out with this. I learned that orange doesn’t print to clear vinyl particularly well.
Luckily a company called Fast Signs in Kingston came up with the idea of reverse profile cutting my window logo on coloured vinyl, as opposed to printing on clear vinyl. I also had a large copy of the droog’s face printed in black vinyl for the case’s other side panel.
The orange vinyl was then placed on the acrylic window followed by black vinyl then frosted vinyl. This way, the graphic was a perfect match to the bright orange paintwork.
I also had some smaller transparent text stickers made for the front of the case and for an external hard disk drive caddy. The caddy was also powder coated orange to match the PC case. In addition, I spray-painted the motherboard heat sink shrouds and the PCI brackets orange too.
To tidy up the inside I braided all the power cables and spent a fair bit of time cable tidying throughout to minimise clutter and to improve airflow. It’s something I really wanted to get right and I’m glad I took my time.
Finishing touches and Overclocking
There are four 12in UV cold cathodes lamps inside the case, which make the UV orange anti-kink coil springs glow very brightly. An orange triple laser LED unit illuminates the XSPC pump and reservoirs, and a white one illuminates the face on the side panel window.
Xigmatek 120mm LED fans on the radiators glow orange and white, and the exhaust fans on the rear of the case glow bright white. The motherboard and soundcard also have small white LEDs too. The lighting is something I’m particularly proud of and really makes the case stand out.
As well as having a fast CPU and three fast graphics cards, I decided I needed some speed in the storage department too to keep up with everything else. For this I chose three Intel X25-M 80GB SSD drives. I was a little sceptical at first, but the sheer performance boost of these three drives in RAID0 has simply blown me away!
StarTech.com from the States provided the backplane for the SSDs - it holds up to four 2.5in HDD’s in a single 5 1/4″ bay! It’s hot-swappable and lockable too. The quality, features and ease of installation make this a great addition to the case.
To achieve this, the system needed a vcore of 1.36v. The CPU runs at a maximum temperature of 72°C even after running the smallFFTs stress test in Prime95 for several hours. I can bench at 4.2GHz and even pass a Linpak torture test, but when I tried to run Large FFTs in Prime95 (4096 FFTs to test RAM) the PC would blue screen within 20 minutes or so no matter how many volts I was putting through it.
Other tweaks I made were to raise the CPU PLL voltage to 1.895v, the QPI/DRAM voltage to 1.35v and the DDR3 to 1.65v. I also increased the core speeds on the three GeForce GTX280s from 602MHz to 730MHz, the stream processors from 1,296MHz to 1,470MHz and the memory from 1,107MHz to 1,275MHz.
Thanks to Sponsors
I have been completely overwhelmed by the attention this build has received. I built the rig purely for fun and thought I’d share the progress with other Custom PC readers by creating a project blog on the Custom PC website.
Since then the BBC have filmed a feature for its technology feature on Overclocked Orange and PC Modding - it’s also won Readers Drives too. I’m chuffed to bits to be honest and I’m pleased people seem to like the project.
A very big thank you goes to Rob and Marcus at WCUK, Gary at Sidewinder Computers, Solphorinc, Fast Signs in Kingston, Custom PC Magazine, Scan Computers, and all of the community for your help and support.
