Hi everyone, I’m halfway through a new vintage mod project and I figured it was a good time to share a few pics. This is a follow-up to the mod of the IBM PS/1 2121 I posted a few weeks ago (The PS/1 2125 - ROG). Objectives: - Switch the box from a PS/1 2121 to an IBM PS/1 2011: the original PS/1, twice as thin: 26x7x30cm (width/height/depth). My PS/1 2011, in working order, keeping this one - Bring as little modification to the original box as possible, except the paintjob, and especially preserve the way it slides open. - Keep the same CPU/MB and GPU (Asus ROG Impact VI et EVGA GTX770 SC) - To do so, give up on both closed-circuit loops previously used for a single custom watercooling loop, with an external cooling tower. - Having the tower’s design somewhat match the PS/1 look, especially air intakes. Elements of the loop: - CPU Block EK Supremacy MX - GPU Block EK-FC770GTX with EK-FC780GTX Ti rear plate - Pump-Tank Combo EK-SBAY DDC 3.2 PWM - Radiator EK Coolstream XTC 280 - 2 x Be Quiet Silent Wing 2 140mm fans - 4 simples 13/10 fittings and 4 L-shaped Alphacool 13/10 fittings - 2 Phobya Quick Coupling Valves, 13/10 - Red EK coolant fluid - flexible Alphacool 13/10 tubing Other parts : - A flexible PCI-E 16x riser - SD Card Reader (Akasa AK-ICR-13) Step I : The cooling Tower This PS/1 case is so small that I didn’t find a way to host the motherboard and graphic card together with the pump and tank. I chose a combo pump/tank instead and decided to put it in the external tower. As for my previous mod I have few tools and mostly used spare acrylic sheets. The tower dimensions are 15,3(width)x36(heigth)x13,5cm(depth) and the shape of the radiator let me install a SD card reader at the bottom. Just to have a first idea, I stacked these elements together with a cardboard version of the grill: And here are the blueprints (made with Draftsight): Sides and vertical parts of the grill (acrylic 2,5mm) : Top and bottom parts (acrylic 5mm) and horizontal parts of the grill (acrylic 4,5mm) : A first try at putting things together: Cleaning and gluing the grill Aluminum radiator rails Front view, once assembled and painted For the paintwork, I tried to get the same texture as the PS/1 case using a sandy texture layer, plus a black layer… not quite like the original but still ok. The grill is removable for maintenance The back is still messy I still need to simplify and braid the cables, and I will also make part of the tubbing rigid so that I can close the case, to get a cleaner look. Front view with temporary braiding and quick coupling system installed Close-up on connections Step II: modification of the PS/1 case itself Over the summer I modded the case a bit with the following objectives: - Keep the upper part clear of any modification in order place the screen on top, in the original PS/1 spirit. - Cut/drill the bottom of the case : to make an intake for the SFX PSU, and to fix it as well as the motherboard. - Mod the back of the case to accommodate the I/O backplate, as well as connections to the cooling tower. - Add something to hold the PCI-E 16x riser. Before we start… Front view of the original case On my previous PS/1 mod someone told me it was a shame to do make use of the original 3.5’’ hole… I don’t have much space as the GPU will be right behind, but at least I will put USB ports there and the eject button will be recycled as a power-on switch. Rear view Quite a bit of work to come… with an obvious issue of rigidity in the end. Those PS/2 ports are exactly the size of the pass-through Phobya quick release valves I bought… at least that one less cut-out. Freeing space… (parts of) what will get in Clearly this will be quite packed in there… the SFX PSU barel fits in height, there is not enough width to use a rigid riser… hence the use of the flexible one so that the GPU and MB overlap. Cutting out the bottom of the case Work on the backplate Some additions From bottom to top : - The PCI-E Riser holder - A plate to reinforce the backplate - The PSU holder Front plate, painted The front USB/LED/Switch panel and the power on LED The bottom of the plate, painted On second thought I will replace the fake carbon by an actual thin sheet of carbon fiber or simply acrylic. Overall view when assembled Step III…. hmm… step I bis, back to the cooling tower Here is where I had left it : quite a mess with tube out of the case. And here is a rather tidier layout, using L-shapped fittings (3x G1/4 ->13/10 from Alphacool and a generic 13/10 -> 13/10). I kept the flexible tubes, no real need to go for hard-tubing. As a final touch I made a rear grill out of a spare steel grill sheet. Note to self: this badly cuts, don’t forget gloves next time. And here is the final view (just need to remember to conceal the power cable of the pump): Next steps (hopefully soon): assembling the components and testing the loop. Speaking of which, I am still looking for a PCI-E 3.0 certified replacement for my noname (and potentially non-reliable) PCI-E extender. I spotted the Lian Li PW-PCI-E38. Anyone used it before? Any feedback? It seems more available than the 3M I was looking for initially.
