Hi,
Just signed up and first time post on here.
I’m looking for advice on upgrading an existing HTPC so it can act as a reliable client PC for game streaming from my main desktop using Sunshine and Moonlight. My host PC (Atlas) is an AMD Ryzen 7 9700X with an RTX 5070 Ti, 32 GB DDR5-6000, NVMe storage, running Windows 11. Atlas connects over stable Wi-Fi and Sunshine logs show clean NVENC encoding, no dropped frames, no encoder stalls, and no network send errors. Network latency is low and consistent, and normal video streaming is flawless, so the host and network have been ruled out.
The client HTPC is an older system with an i5-2500K on a Gigabyte Z68 board, 8 GB DDR3, and a GTX 660 Ti, running Windows 10 in a SilverStone LC16 HTPC case. Moonlight logs on this system show repeated video decode queue overflows, waiting for IDR frames, and audio packet overflows. The GPU lacks HEVC Main10, AV1, and HDR support and falls back to H.264 which struggles to maintain smooth 60 FPS decode. . My conclusion so far is that this is a client-side decode limitation, not a host or network issue.
My plan is to reuse the LC16 case, PSU, storage, but replace the motherboard, CPU, and RAM. The HTPC will be client-only (no local gaming), used for Moonlight streaming, media playback, and general living-room PC use. I’m targeting smooth 4K60-120 output with some future headroom for a planned 4K OLED TV. I’m currently undecided whether a discrete GPU offers any real benefit here, or whether a modern Intel iGPU is the better, simpler option.
I’d appreciate advice on which Intel CPU generation and chipset make the most sense for a Moonlight/HTPC client in 2026, whether DDR4 or DDR5 is the smarter choice given current awful pricing, and whether there are any known HDMI, HDR, or iGPU quirks I should be aware of. The goal is a quiet, stable client (build it once and forget it) rather than maximum performance.

Welcome to the forums, newcomer!
I intend to adapt the LC16 setup, using the PSU, storage, but changing the motherboard, CPU, and RAM.
Please share your location, budget, and preferred purchase site. Also, provide details about the PSU in your Silverstone LC16 chassis—specify its make, model, and age. If the PSU is as old as the processor in that case, you’ll need to replace it too.
Regarding cases:
Is this the correct one?

I’m based in Australia. My budget allows for a practical client-only HTPC setup, around AUD $700 to $1,000 covering the motherboard, CPU, and RAM. I’d like to shop at Australian shops such as Centre Com, Scorptec, Mwave, and PCCaseGear, though I’m willing to consider alternatives if needed.

The power supply will be an Antec TruePower 750w unit. Although it’s a bit older, it has proven dependable. The case is the correct SilverStone LC16M model. This HTPC is intended solely for media consumption—primarily Moonlight and Sunshine content—without local gaming, focusing on stable 4K60 performance.
