I know everyone here on Roon has a PC/Mac/Linux computer to play and possibly upsample music files. if you feel the need to upgrade this may be a good option.
Windows 10 pro based PC, 4 months old that was made for streaming music and up sampling music files to DSD512. This PC can handle HQPlayer (2s filter) at DSD512. It can handle all HQPlayer filters at rates under DSD512 (DSD256,128,64 and all PMC),
I built this for a friend who after 3 months decided to give up PC streaming and focus on Vinyl and RTR tape playback (he likes easy buttons). The original motherboard failed, diagnosed as video output failure. I installed a new motherboard in the PC and all is back to perfect working order.
Parts in this PC
Case- Thermaltake Core V21
CPU- Intel i7-4790K (base frequency 4.0Ghz with turbo to 4.4GHz)

The above in parts cost is $907, I will sell it for SOLD. Motherboard is brand new other parts about 3 1/2 months. prefer USA or Canada sale.
I also have a Western Digital Black 2TB HDD (7200 RPM) that was used for music storage which I can include for an additional $85, it also is 3 1/2 months old.
This is a very quiet PC, it does have 3 fans (200mm input, 120mm output and 120mm for the CPU radiator cooling). Max temperature (CPU) I have seen while up sampling to DSD512 is 61C, ave is high 40’s-low 50’s.

There is plenty of room for expansion 1-PCIeX16 slot, 1-PCIeX8 slot, 1-PCIeX4 slot, and 2 more slots open for additional memory, tho I find 8GB sufficient. A very capable GPU can be added for apprx $120 that has a compute capability of 6.1 (the highest compute capability currently listed on Nvidia’s Geforce web site)
I have 100% feedback on Audiogon (quadman) and eBay (Ilovetubes)
