So I pulled together some components and built an EGPU for my ROG Ally X. I think the results are fantastic and wanted to share:
Box moves between my office (3440x1440), home theater (1920x1080), and living room (4k). Performance has been stellar with the office sitting at 70-90 FPS ultra, home theater at 140+ FPS ultra, and living room between 30-60 FPS ultra. Temps are always great even at load. Drivers were a pain at first, but that was due to a bad PCIE extension cable and a PCIE cable to the GPU that wasn't fully seated. Had to tweak the case a hair, but the PCIE board sits nice and flat in the base of the enclosure.
For specific games:
Plague Tale Requiem: Running 4K Ultra across the board getting 45-60 FPS.
Space Marines 2: Running 4K Ultra across the board getting 35-45 FPS.
Dying Light Stay Human: Running 4K Ultra across the board getting 35-60FPS.
Starfield: Running 4K Ultra in the busiest cities and getting 30-60FPS.
Going to the office and projector - runs even better... On the projector I can get stupid and turn on Raytracing and the FPS are still great.
Enclosure:
Mechanicmaster IF-11 (90 Bucks Open Box)
Dock/Board 1:
Aliexpress v1.6 UT3G @ $130
Dock/Board 2:
Dock for peripherals and power
GPU:
Reference AMD RX7900 XT (Got it for $569 refurbished)
PSU:
Corsair SF850L (Refurb for 90 bucks)
Air Cooling:
Silverstone Shark Force 160 Intake Attached Magnetically to the Case
2 x Arctice P12s Exhausting Out the Top
Fan Controller:
Fan Controller I Snagged for 10 Bucks
L-Shaped Thunderbolt 4 Cable:
TBolt 4 Cable Built Like a Tank
Odds and Ends:
3D Printed I/O Cover
Tiny, Adhesive Rare Earth Magnets for the Fan
Replacing all the PSU cables with sleeved ones soon... The ones that came with the PSU are, well, awful.
Some decals to pimp the exterior of the case.
