Ordered a Roon Nucleus Plus

I've been using a robust Windows10 Pro Dell laptop (with an external USB connected hard drive) for streaming and storing my CD quality and abover AIFF files.  I have the Tidal Windows app and the Roon core running on this machine.  As more and more updates are pushed out to that machine, it's streaming performance has suffered, mainly some process I can't identify seems to temporarily pause it's connectivity to the network.  Since that machine runs Windows, which has all sorts of processes running not related to music delivery, I decided to "take the plunge" and yesterday ordered a Roon Nucleus Plus.

I'll typically have the external hard drive connected to the Nucleus, but when I purchase new music will connect it to the Dell to store the files on the drive, and back the files up to the cloud.

I've had really good luck running Roon, the program seems really stable, and the sound quality is excellent.  Wish me luck making the transition!
My current setup is based on a pretty powerful Dell Windows10 Pro, I7 quad core processor, 16 gigs of memory, but with some of the other things running on it (like the HP app to print to our all-in-one), that and other things that are running at the time, causes streaming to pause, sometimes freeze.
Back in the day I used an Autonomic MMS-5A server, no problems delivering either Tidal or my library of hi-res AIFF files.  I still have this server, but the app is somewhat "long in the tooth".

When I'm done with this transition, I'll have my library on a 4tb USB external disk drive, and be able to use the Dell to purchase tunes from HDTracks.com, record CD's and backup the drive to my Google Drive account.  When not doing all that, I'll have it connected to the Nucleus Plus.

Thank you everyone for your kind consideration and help with this.  I hope to receive the unit later this week, need to be out of town for about a week, after that will make the transition and provide an update.
What would it cost to build a server to compete with the Nucleus +?  It seems like you could build an equivalent server for much less.

See my my post above regarding hardware costs, Roon operating system software is free.  The Roon program is not.
Yes, it may have been a bit cheaper to build something to do the same function, but from what I've read the Roon products are top notch, and for people like me, a computer guy, if I had the time and the desire, I certainly could have saved a few bucks going the route of another piece of hardware, but my time is so limited, I'd rather get a product from the vendor, supported by the vendor, etc.
I just installed a nucleus + a couple weeks ago.  Also of course Roon.  I have been very impressed at the sound.  The program is great it seems, rather quirky and doesn't make a lot of common sense to me but I'm figuring things out.  I am noticing now it's starting to get sluggish.  Like when the next track starts to play I'm getting the beach ball for 10 seconds or so.  If I click the app from another app I get a delay.  It's a little concerning since there are many on the Roon community that complain of running slow issues.
