I've currently got a home server setup, using a SATA expansion card, but I've got an LSI HBA ready to swap in, but due to the case/space I have, I intend to mount my drives in a seperate enclosure, so I've been doing some research into different SAS cards, expanders & external connectors.

My current plan is to connect as follows:

HBA (SFF-8087) to a converter mounted in the PCI slots (SFF-8087 internal to SFF-8088 external) (0.5m SFF-8087 cable used)

External 2m SFF-8088 to SFF-8644 cable to the HDD enclosure.

Adaptec AEC-82885T SAS expander in HDD enclosure

SFF-8643 to SATA connectors (0.5m)

Anyone with more knowledge of this able to comment if this is a stupid way to do it, or if it'll be absolutely fine? And if it's stupid, what's stupid about it & what should I do differently (I know ideally I'd have an HBA card that has an external connector, but the one I have doesn't have one)?

Nothing really wrong with doing that. Same thing enterprise storage systems do, especially back in the day. Just connect the enclosure to the same UPS as the controller/server and secure the cabling well.
