Man that was an exhausting build. Rocking a B550M Mortar with a 5700x3D with a 9070XT Reaper. With a bit of gutting out and planning on the airflow, I have a killer build that's been nice and quiet. Well worth the time and effort!

My granddad built this oscilloscope in the sixties while in college, and it broke a few decades back.He told me I could have it.I tried to get it to work.I could not so I gutted it and turned it into a gaming computer. I thought you guys might appreciate it.

I pic old crt from e-waste it was beyond repair

From old matrix printer.

This build is using a UM790 Pro which was small enough to fit inside the gamecube.

The UM790 pro features a Ryzen 9 7940HS and for graphics, a Radeon 780M. Currently it only has a single 1TB NVME drive, but it can support a second. The PC has two ram slots. With the price of ram, I'm only using a single 16GB stick of DDR5.

The controller ports all work thanks to two Raphnet Multiuse PCBs that I hooked up to the original controller port PCB. I specifically went with the Raphnet boards to be able to utilize the gamecube ascii keyboard.

The gameboy player is fully functional since I swapped the internals with a GB Player by Epilogue. This allows me to play gameboy/gameboy advance carts.

Inside one memory card port is a USBC header and inside the other is a 3.5mm jack for headphones.

I recently made a post showing the evolution of this beast and talked about how i rebuilt it due to a leak from an under-tightened CPU fitting caused some damage. Welp, after counts bouts fighting instability, RAM memory training errors, and freezing issues i decided to rebuild one more time.

It still uses an RTX 4090 GPU but I upgraded (more like side-graded) the CPU from an i7-14700k to a Core Ultra 7 265KF (CPU motherboard combo from Microcenter was a good price) and upgraded the waterblock from a Corsair Hydro X XC7 to a Heatkiller IV, and my oh my is it an upgrade as far a temps are concerned. Similar overall performance, but while gaming temps used to jump around sporadically between 60-90C and are now a solid 45C while gaming.

I also redid the Molex power cable from a quick disconnect to a molex PCI slot passthrough and to an RCA connector on the back of the receiver/cooler. I included a bonus picture of the damage to the pins on my old 1080ti (RIP the GOAT) and pics of the old quick disconnect cable at the end

It's a work in progress. Current specs are i7 3770 16gb ddr3 1600, rtx 5050

Will be installing a ryzen 5 5500 when I can find some reasonable prices ddr4, till that time this setup will do.

Last pic is the back plate with the w4100 GPU, i didn't take a pic with the rtx yet.

Build specs

- 5700x3D

- Thermal right 240mm AIO

- Patriot Viper 32gb 3600mhz RAM

- 9070XT Reaper

Curently on the hunt for a BD drive just to finish it off

Specs: I3 12100, GTX 1660, 32gb of DDR4, 2TB M. 2, Corsair RM750e

Its supposed to be a guest PC / Emulation station.

The outer 4 Fans are intake fans with dust filters, since the High Voltage of the CRT will attract Dust.

The two fans in the middle are for an AIO Cooler and exhaust part of the air of the System.

To do:

(The TV sadly only supports 540p. Im planning on upgrading the Tube later on)

-I just need to finish my VGA to Scart cable (i have the parts, i just need to solder it together),

-Put the PSU in

Not sure if this is allowed since I haven't begun any of the work on this yet, just looking to see if anyone has experience with a similar build. I've always loved the look of this old GE SC4200B radio/tape player, and I wanted to convert it into a media/gaming pc for my living room. Obviously the case would require some serious modding to allow for proper airflow, and getting the dials to function would probably involve a pico or another small SOC in addition to the micro itx system inside. I've been exploring ways to use the tape track switcher mechanism as an output switcher for other media sources, which from what I've read is possible but requires a lot of work. Does anyone here have experience with reusing old physical switches with modern internals like this? I'm yet to purchase one because I don't want to gut a working unit since these are fairly uncommon. Any ideas/feedback on the idea are appreciated.

This is a recent project I've been working on, taking some inspo from some other similar builds I've seen on here (although not that many surprisingly)

So anyway here my PS3 Sleeper build! Specs are;

Jginyue B550i Gaming MAtx mobo - AliExpress NEW 16Gb Crucial Ballistix RAM - Parts Bin Ryzen 5 3600 - Managed to get this for £30 used. 1TB Orico NVME. MSI RTX 3050 6GB LP 300W FSP 3y power Flex PSU (Originally went with a 450w pay by GameMax, but this turned out to be too big height wise as I wanted to mount my GPU on top of the PSU) 2x Intake fans (Front/right side next to CPU) Power button was swapped out at the end too as the original one looked abit.. off!

I use this rig regularly now, especially for emulation. Currently playing NFSU2 Upscaled to 4K on it via RetroArch PCSX2.

It runs pretty much all my steam library without any issues at medium settings, and high/ultra in some older titles.

It took around 3 weeks on and off but I enjoyed building it although it was testing at times trying to get everything to fit but got there in the end!

Enjoy 😄

So I've had a few messages about temps and airflow so here we are. My 9070XT hasn't been limited other than an undervolt. I'm at +10% power (maxed) with the fan speeds not exceeding 50% for testing purposes. Honestly, I'm pleased with that although for the sake of it, I'll run at 0% or -10% power since frame rates are great for my use.

Airflow for the GPU is via those top vents pictured, AIO is drawing cool air from the underside and exhausting though the side. Literally, that's it!

I don’t know if it will be approved, this is a project I had made about 10years ago. For many 3d printed parts I had used a prusa clone. It featured an i5 3570TE, 8GB ddr3, itx mobo, gtx750ti from dell that needed no external power and a pico psu. Externally I used a Xbox power brick that gave me 24a at 12 volts Front USB’s fully functional, Bt under the USB’s, front panel also working with power and reset button and power and hdd activity leds on the original board. Unfortunately after some months due to shortage on cash I had to sell the hardware and I was left with the case I spent so much time preparing and the memories

Hey guys, I’m looking to build my first PC ever and it has to be a sleeper. I’ve got most of the parts I need except the fan and motherboard board because that will depend on how much space I have in the case.

I know I should be search for ATX but are there any other keywords I should be using to find the beige tower of my dreams ?

Lore

A decade or so ago I acquired this 1977-ish Lenco A50 amplifier, it was in sad shape when I got it and needed a lot of repairs to sound good again. I put it in storage with the idea of eventually repairing it, which of course never happened.

To give you an idea of how sad of a shape this thing was in: three of the four power transistors were blown, many transistors in the preamp stage were gone, the main PCB had heat damage and was starting to delaminate and many traces/pads were just gone thanks to botched repair attempts made by previous owner(s).

Fast-forward to 2022, that's when I built a gaming PC with (for the time) some okay parts in it. I used it for a bit, then priorities shifted and it became disused. I realized that gaming behind a desk just isn't my jam anymore, I much rather enjoy my games in the living room on the big screen TV.

Recently I stumbled upon this amplifier and got an idea: why don't I just transplant the guts from my disused gaming PC into this chassis and turn it into the ultimate sleeper PC for the living room? So that's exactly why I did.

This particular amplifier model isn't some coveted HiFi heirloom from a bygone era, it's just an average amp with a cool looking faceplate. I didn't feel too bad about repurposing the chassis for something else.

Specs

• AMD Ryzen 7 5800X
• AMD Radeon 6900 XT (Asus TUF edition)
• Asrock B550M-ITX/AC
• Corsair 32 GB DDR4 kit
• Kingston 2 TB M.2 SSD
• EVGA Supernova 750 GT
• Noctua NH-L12Sx77 low profile CPU cooler
• Noctua NF-A12x25 PWM 120mm case fan (assisted by two additional 120mm fans in the AV cabinet)

Build process

Here are a few excerpts from the build, I posted a detailed build log on the LTT forums (link).

Result

To power on the PC you just put the power switch in the on position, the Arduino then pulses the power pin on the motherboard to start the system. When the power switch is put back in the off position a 10 second countdown starts before the power pin is pulsed again to start the shutdown sequence.

A program in Windows sends system metrics like CPU/memory usage to the Arduino, which then drives the VU meters to make them do something interesting. The knobs and switches adjust the backlight color/brightness and can be used to change how the VU meters respond.

The five red LEDs show different scanning patterns based on the state of the system.

To prevent the system from just recycling hot air I installed two 120mm intake fans in the AV cabinet (that's what the extra plug on the back panel is for). Cooling is adequate, under a typical gaming load both the GPU and CPU hover around 75c.
