I agree. It's a wonderful machine and looks very cool. Especially with the SM.144 monitor and also the even more gorgeous (IMHO) NEC Multisync 1990SXi LCD monitor
I recently got hold of. With the computer, keyboard and monitor in a cream-like colour it looks quite futuristic and "different" from the usual boring, generic looking PCs. Here's a picture of the TT and 1990SXi, identical to the Mega STe:
Unfortunately its motherboard won't fit in a 19" rack enclosure (unless you get a very deep one) so I'll most likely sell mine once I get it 100% working again and keep the STe instead. A complete Mega STe (recapped PSU and new fan) with the original internal SCSI interface and hard drive, MonSTer board with a CF-adapter, upgraded 1.44MB floppy drive/controller and possibly also an Atari SM-144 monitor and maybe even a full Notator SL package and perhaps even some add-on MIDI hardware should make it an attractive buy for someone who's looking for a stable and efficient MIDI computer, even in 2017. We'll see when I get the STe finished.
Being recased with various hardware add-ons (realtime battery-backed clock, TOS 2.06, 1.44MB floppy drive/controller interface, ST_ESSC/RSVE for additional and faster serial ports, and a MonSTer board for silent/fast CF or SD-card storage, Flash ROM and 8MB additional ALT-RAM) my 4MB STe should be "almost" like a Mega STe, but I will miss the 16MHz although it's not used with Notator SL (which will be the main purpose for this computer). Neither can a VME graphic board be used with Notator, so I haven't bothered with it (nor have I ever come across anyone selling one).
As I understand it, Cubase is better in this respect.
