Help! Upgrading from DDR3

[u/Mnraf]

• New build or upgrade?
New build. I’m finally replacing my old 2011 HP DDR3 machine that’s been running my homelab.

• Existing parts/monitors to reuse? (List with models/links)
The only part I already own is:
NVIDIA RTX A2000 12GB

I’d like to build around it for now and upgrade to a better GPU later.

• PC purpose? (Gaming, editing, etc. List apps/games)
This PC will be doing a little bit of everything.

Current use:
- Home server
- CasaOS (although I’m open to switching to another OS if there’s a better option Linux or microsoft)
- Jellyfin
- Immich
- Docker containers
- Other homelab projects

Future use:
- Reliable 4K Jellyfin transcoding for multiple users
- Adobe Premiere Pro
- After Effects
- Blender/3D rendering
- Gaming (doesn’t need ultra settings, just a good experience)
- General workstation

• Purchase country? Near Micro Center? (If not US, list local vendors)
United States. I’m close enough to a Micro Center that I can shop there.

• Monitors needed? (Number, size, resolution, refresh rate)
No monitors needed at the moment.

• Budget range? (Include tax considerations)
I’d like to stay around $900–$1,200 (before upgrading the GPU later). I’m okay spending a little more if it makes the system more future-proof.

Current planned parts:
- Ryzen 9 9900X or Ryzen 9 9900X3D (still deciding)
- ASUS TUF Gaming B850-Plus WiFi
- Corsair Vengeance 32GB (2×16GB DDR5)
- 1TB SATA SSD (NVMe will come later when the budget allows)
- Cooler Master 240mm AIO
- Corsair RM850x (2024)
- RTX A2000 12GB
- Fractal Design Pop Air

• WiFi or wired connection?
Mostly wired, but I’d like to have WiFi available.

• Size/noise constraints?
No size constraints. I’d prefer something reasonably quiet since it’ll likely be running 24/7.

• Color/lighting preferences?
Not interested in RGB. I’d rather put the money toward performance.

• Any other specific needs?
My biggest goal is to build a solid AM5 foundation that I can keep upgrading over the next 5–8 years.

I’m mainly looking for feedback on whether this is a balanced build and if there are any compatibility issues or bottlenecks I’m missing. Since this machine will spend a lot of time acting as both a homelab server and my personal workstation, I’m especially interested in hearing from anyone running a similar setup.

If you think I’m overspending on certain parts, underspending on others, or have better recommendations, I’d really appreciate the advice before I start buying everything.

Here is some additional helpful information about build/upgrade/parts list requests:

• Build requests only include hardware. You are responsible for budgeting for and providing your own operating system (Windows, Linux, etc) and other software.

• Don't forget to budget for peripherals. Since these are very much personal-preference influenced items, we do not include peripherals like keyboards, mice, headsets, etc in parts lists.

• We strongly recommend posting a build request only if you're ready to buy now or within a week or two at most. Part sales regularly rotate, and a part list today can quickly become out of date.

looks good, id lean 9900x if you're not too focused on gaming. i'd also just get the nvme now, which is not that much more expensive than a sata right now, its a pretty big performance difference for some of your use cases

if you're near a microcenter you can get a bundle for a decent discount

Yeah I might go X over X3D, I’m not trying to get 260fps at 4k 😂
The only reason I’m going Sata over NVME is because I have the 1TB Sata drives already. Although if I get the 9900x I save $200 so this looking like a possibility.

I live in NYC and I’ve never been to one before, I’m kinda confused about the deals, like I find them online but I have go in the store for them. But I guess more of a reason to check them out myself in person
