Oh dear, long reply lost into the ether.
I have run RoonServer on my Synology NAS, which has a older CPU and 3GBs of RAM, it worked fine, save searches in Roon were noticeably slower. I wouldn't recommend it for an optimal experience. I believe your NAS only has 2GBs of Ram which is going to be less than optimal.
Maximum amount of usable memory on a 32 Bit OS is 4GB.
If you decide to go down the Roon Core Kit path, you could leverage you existing NAS, and add either an Intel NUC5/NUC6 running either Core i3/Core i5. A minimum of 4GB of memory is required and 64GB of storage.
i.e. an Intel NUC6i3 with 16GB of RAM & 256GB M.2 drive would set you back ~ $490
i.e. an Intel NUC6i3 with 8GB of RAM & 256GB M.2 drive would set you back ~ $420
Etc...
