It's my Merida Ride 400 the frame isn't worth much now it's discontinued and superseded by the Scultura.
I was looking at the Reilly T325 frameset, it's 105 spec if you purchase it from Reilly, I would use their own branded seatpost, and use a new headset, stem and bars, my DCR wheels aren't that old and the groupset isn't that old on the Merida either.
I was kinda fielding the idea to see if it was daft, I can ask the mobile mechanic I use about the crankset, he sold the Merida to me and upgraded it recently as well so he knows the bike well.
I also have some 105 5800 components I can still sell off as well.
EDIT: Merida is currenty 105 R7000 spec groupset.
EDIT: Other frameset was VN Boreas I was looking at.
Be aware that neither frame has mounts for mudguards or racks. If that is your preference, then apart from checking rim brake caliper drop height. You're good to go.
If you fancy something a little more multi purpose, this may whet your whistle
