MikroTik added RB4011 support to RouterOS in late 2018, and it's the obvious step up from a hEX for anyone who wanted ten ports and a 10G uplink without a fan. Inside is the Annapurna Labs AL21400, a quad-core Cortex-A15 that MikroTik also used in its carrier-grade RB1100AHx4, with 1 GB of RAM and 512 MB of NAND. You get ten gigabit ports, one SFP+ cage, IPsec hardware acceleration and passive PoE out on port 10. The RM version comes in a black metal case with rack ears in the box, and there's a sister model with Wi-Fi, the RB4011iGS+5HacQ2HnD-IN. It ships with a Level 5 license and RouterOS v7. In a home lab it makes a quiet core router with a 10G link to a switch like the CRS326, and it has more than enough for MTCNA and MTCRE practice. Power comes from an external 24 V adapter, so make sure it's in the photos.
Lab check
Should come with it
Check the listing photos against this list, and ask the seller about anything you can’t see. A missing piece should come off the price.
RouterOS 6.43.13 fixed port 10 failing to negotiate 1 Gbps, and 6.44 fixed SFP+ links at 1 Gbps, so update an old unit before blaming the hardware. Otherwise most trouble is the previous owner's config and missing parts.

Buying guide
We'd buy thetroubleshooter's used RB4011 at $160 with free shipping, since the photo shows the 24 V adapter, or engineeredseller's sealed new one at $220 with the rack brackets and screws. There are at least 25 for sale and most are new stock. Most used ones ask $140–168 delivered, new US units $210–280, and new imports from Italy, Latvia and Germany $250–413. The Level 5 license is bound to the router and stays with it on resale, so the checks are the sticker, which should read RB4011iGS+RM (a code ending 5HacQ2HnD-IN is the Wi-Fi version), and the 24 V 1.5 A adapter, which the two cheapest leave out. Skip cybertrading_gmbh's at $413 delivered, a VAT-inclusive business listing from Germany with $167 shipping.
