Building a used pc

Recommended Posts

Posted · Original PosterOP

I built my real gaming PC 2 years ago. I'm not really wanting to upgrade right now, but I thought it would be a bit of fun to build a used PC with parts off mostly eBay. I'm willing to buy the case and psu new, but the rest of the parts I want to by used. I might also be using steamOS just to give it a try (I know that the game compatibility isn't great) Thoughts on this build?

Here's the part list:

CPU: Intel Core 2 Quad Q6600 2.4GHz- $45 in CPU/Mobo/Ram Combo (eBay)

Motherboard: Intel DG31PR LGA775/Socket T: $45 in CPU/Mobo/Ram Combo (eBay)

GPU: EVGA Gtx 670 Superclocked 4GB ~ $70 (eBay)

RAM:Kingston 2x2GB 800MHz, 4 GB DDR2 - $45 in CPU/Mobo/Ram Combo (eBay)

PSU: Seasonic S12II 620 BRONZE, SS-620GB  ~ $50 (Amazon)

Storage: 750 GB Seagate Barracuda Hard Drive (7200 RPM) ~ $26.60 (eBay)

Case: Corsair 100R ATX Mid-Tower ~ $50 (Amazon)

Total: $241.60

 

Things I Have Thought About:

- Used Hard Drive Failure

-CPU is most likely a bottleneck for the 670

-PSU a little overkill

-Motherboard is a little sketchy

-Using an aftermarket cooler for cpu?

what's your budget for everything? the S12ii is old+missing protections, so get the CX550 instead. what's the city you're in?


CPU: AMD Ryzen 7 1700@3.8Ghz Heatsink: Gelid Phantom Black GPU: Sapphire RX 5700 XT RAM: Qidian DDR4 2x8GB 3000Mhz mobo: Biostar X370GT7 case: Fractal Design Define C PSU: Superflower Leadex Gold 650W

One of the few parts that I wouldn't recommend buying new is the HDD.

You could buy an HDD (500GB) for $30 (or less) without having to worry if it works.

My budget isn't set, but less than $250 would be fine.

Also, I live in a small town in NJ

Oh wow ok, I haven't looked into buying old desktops. What are the chances that the motherboard in that Dell is ATX and not some OEM part, because I might want to transplant the CPU/RAM/Mobo into a new case?

That's the restriction here, strictly speaking you can't. While the motherboard is micro-ATX, the front panel connector for the power button is proprietary. If you could identify the two pins that were for power on, it might work. But unless you've built tons of PCs before, it's probably not worth it.

Alright, then do you think it's at least effective to take out the RAM, CPU, and HDD out of an old desktop?

Those parts are okay. But generally speaking, the motherboard, case and sometimes even CPU cooler are all tied together and are proprietary. Separating any of the aforementioned parts would mean they would not fit with other standard parts.

the motherboard uses standard 24-pin and 4-pin psu connectors and is standatd MATX, but the I/O connectors look proprietary. you'll have to look up a manual online and figure it out manually if you want a case upgrade.

Ok I'm actually planning tomorrow to drive over to a used PC shop just to see what they have. But if they don't have anything, does this dell (and oem pcs in general) have standard mounting holes for an ATX psu? I assume they do if you can replace them

yeah it's standard atx mounts.you'll have to check, standard tower prebuilts usually have normal PSU mounting holes but you'll need to check manually.

Checked the manual, it doesn't specify the power supply form factor but I found some forum posts about replacing the power supply that say it's atx.

you can replace it just fine. but other towers might not so you'll need to check if you're planning on those. the I/O connectors may be different as well so if you want a case upgrade check if any forum posts or manuals online say anything about the layout.

Sounds good, 1 more question. Do you have any tips for searching for the old desktops. ebay's filters really don't help b/c most hardware is listed as "unspecified". Do you think it'll be more effective just to search "Core i5 2nd Gen Desktop" or something like that?
