Yes
just noticed the bleeder resistors are not shown in the schematic but they are in the circuit
Hey, it looks good. I see KBPC bridges. You sure did your homework.
Actually, I'm extremely jealous about homework that
requires jamming out at 3 a.m. Wow!!
Anyway, there's an exhaust fan, so are there an air intake holes underneath the heatsink? I ask this because I'm a computer network guy (before I got tired of it and quit) and I've seen so many computers with an exhaust fan, yet no possibility of cool air entering the enclosure. Oops, stuck computer.
By the way, CoolerMaster (availability Newegg.com) makes incredibly quiet fans, including the 1800RPM model with blue LEDs for fun. Quiet fans are good for when you don't have temp based control.
Other way, could use a super-fast fan like Zalman 3k RPM, two bimetallic springs and two power resistors, corresponding to off, low, high, based on temperature. Analog power makes buzz-free fan. Inexpensive bimetallic springs with connection terminals can be found in inside attic ventilator fan thermostatic activator boxes, at the hardware store. That's even more fun with LED fans because the light level changes on temperature.
On the speaker output for the subwoofer channel, you might want to hook up both speaker terminals, so to avoid a do-nothing connection on the back panel. Just claim that it can run 1 or 2 subwoofers.
Thinking about that front panel, you could make an addition on front, like a bit of thin Birch panel or veneer, sanded with #0000 steel wool and sprayed with Rustoleum Clear Lacquer (several very, very thin coats) should come out about the same color as the creamy color steel, but much extra "zoot" factor.

There's a lot of other similar color materials at the home improvment store or hardware store. Actually, any "warm" color could potentially work in harmony. Just preview before you glue.
